Abstract:

In the mid-eighties, the development of radioactive-ion beams enabled the exploration ofregions of the nuclear landscape away from the valley of stability. Close to the neutrondripline, in the light neutron-rich region, halo nuclei were observed. These nuclei exhibit asurprisingly large matter radius and a strongly clusterized structure. These two featurescan be explained by the weak binding of one or two neutrons which allows them to tunnelfar from the rest of the nucleons, surrounding the nucleus by a diffuse halo. These nuclearstructures have challenged the usual description of the nucleus,

Abstract:

The Bethe-Weizsäcker cycle consists of a set of nuclear reactions that convert hydrogen into helium and release energy in the stars. It determines the luminosity of low-metal stars at their turn-off from the main-sequence in the Hertzsprung-Russel diagram, so its rate enters the calculation of the globular clusters’ age, an independent lower limit on the age of the universe. The cycle contributes less than 1% to our Sun’s luminosity, but it produces neutrinos that can in principle be measured on Earth in underground experiments and bring direct information of the physical conditions in the sol

Abstract:

The CNO cycle consists of a set of nuclear reactions that convert hydrogen into helium and releases energy in stars. The cycle contributes less than 1% to our Sun's luminosity, but it is responsible for detectable neutrino fluxes that can bring direct information of the physical conditions in the solar core, provided that the nuclear reaction rate is known with sufficient precision. The 14N(p,γ)15O is the slowest reaction in the CNO cycle and estabilishes its rate. The experimental study has been performed both at the LUNA 400 kV accelerator deep underground in the Gran Sasso mountain in Italy

Abstract:

Where did the elements come from? Why are they found in the abundance that they are? These are two of the fundamental questions that the field of astrophysics has sought to answer. The first major studies of elemental synthesis were done in the 1950's and 1960's. Most notable among them was the Burbidge, Burbidge, Fowler, and Hoyle paper [Clayton 73]. This paper set forth the general theory of elemental synthesis in stars and supernovae by means of nuclear reactions. It remains the leading theory for elemental abundance today.As with most theories, the picture of elemental synthesis remains in

Abstract:

The study of the nucleosynthesis of the light elements, Lithium, Beryllium and Boron, plays a key role in understanding of several astrophysical problems related to cosmology as well as to stellar structure and evolution. Moreover, the knowledge of their abundances can be a precious tool for the investigation of the inner stellar structure, especially to understand the mixing processes in stellar plasma. These elements, LiBeB, are mainly destroyed in stellar interior through (p,alpha) reactions induced at temperature of the order of 106 K, corresponding to the Gamow energy EG of a few keV's

The amount of greenhouse gas emissions mitigation required to prevent the most dramatic climate change scenarios postulated in the 2014 IPCC Synthesis Report is substantial. Prior analyses have examined the potential for nuclear energy to play a role in decarbonizing the energy sector, one of the largest contributors to emissions worldwide. However, advanced, non-light water reactors, while often touted as a viable alternative for development, have languished. Large light water development projects have a repeated history of extended construction timelines, re-work delays, and significant capi

This PhD thesis examines the role of nuclear energy in the transition to a low carbon economy in the United Kingdom. Theories of sustainable development, including ecological modernisation, are used to frame its findings and emerging geographies of nuclear new build are explored. Analysis of policy shows that recent narrative from government has been inconsistent on the quantification of the carbon footprint of nuclear energy. The relatively low carbon footprint of nuclear energy, when compared to fossil fuel alternatives, is found to be a significant factor, alongside increased energy securit

Numerous countries worldwide are conscious about the fact that the past and current trends of energy system are not sustainable and a solution needs to be drawn to protect the world energy from a drastic falling.

For a typical horizontal axis wind turbine to run and generate power, a wind speed of at least 5 m/s is required. Countries like Malaysia have less than 5m/s average wind speed.

One-nucleon halo nuclei are exotic nuclei which can be seen as a core around which orbits a loosely-bound valence nucleon.

It consists of the ratio of angular cross sections, breakup and elastic scattering, which removes most of the sensitivity to the reaction mechanism and to the reaction model. In the simple recoil excitation and breakup (REB) model, the ratio simplifies to a form factor dependent solely on the wav

Abstract:

Within this thesis, nuclear resonance fluorescence experiments were analyzed which have been performed at the gamma ELBE facility of the Helmholtz-Zentrum Dresden-Rossendorf and the HI gamma S facility of the Triangle Universities Nuclear Laboratory. The dipole strength up to the neutron separation energy, its distribution as well as its split into electric and magnetic strength were determined. The influence of crucial nuclear parameters, like deformation and neutron excess, on the data was investigated. For the first time a whole set of enriched gaseous targets was measured in the energy r

Abstract:

Two experiments have been conducted to ascertain if a cell with a palladium cathode, a platinum anode, and a solution of H2SO4 in D2O can produce excess heat under electrolysis compared to a similar cell with H2O. In each experiment, two cells were connected in series with constant current. The two cells were identical except for the fact that the heavy water cell used D2O instead of H2O in the electrolyte. Both cells in each experiment employed Pd cathodes, Pt anodes, and H2SO4 in the solution. On a piece of Pd foil that had been cold-rolled and cleaned like the cathodes but had not been elec

Abstract:

The threshold potentials were determined for the excitation energy necessary for low energy electrons to induce chemical reactions of carbon monoxide, and of nitric oxide adsorbed on a gold surface. The reactions were studied as a function of temperature (100 °C to 200 °C) and pressure (1.83 x 10-5 to 6.40 x 10-4 torr). The electron source was a thorium oxide coated iridium filament which was heated by a current between 1A and 3A to keep thermal distribution of the electrons to less than 0.4 ev. The reaction surface was a polycrystalline evaporated film prepared by subliming gold onto a stainl

Abstract:

This work details the synthesis of low density porous polymers, and characterisation with an emphasis on Time Domain Nuclear Magnetic Resonance (TD-NMR). High energy laser physics utilises low density porous polymers to study astrophysical phenomena at high pressures and temperatures in the form of plasma. Low Z, low density Polymerised High Internal Phase Emulsions (PolyHIPE) and aerogels form a large part of these capabilities, however increasingly stringent laser target parameters are now required to develop new capabilities. For low density porous polymers, this demands greater control ove

Foi investigada a correlação entre a energia transversa (ET) produzida e a energia de partículas neutras (En) emitidas em colisões de íons de 28Si (plab=14.6 GeV/c por nucleon) com alvos de Al, Cu e Pb, estudadas pelo Experimento 814 no acelerador AGS do Laboratório Nacional de Brookhaven. A correlação entre a energia transversa e a energia dianteira produzida em colisões com emissão dos fragmentos 2H, 3H, 3He, 4He, 6He, 5Li e 6Li também foi investigada. Foi observado que a energia En dianteira produzida pelas partículas neutras tem uma forte dependência com a energia transversa ET produzida n

Abstract:

In the framework of the exotic clustering in light neutron rich nuclei, an experimental study for the search of 8Li-alpha cluster configurations on 12B was performed. The 8Li-4He elastic scattering excitation function was measured by using the thick target inverse kinematics scattering method implemented by time of flight measurements that allows the elastic channel from the inelastic one discrimination. The 8Li beam was provided by the LNS radioactive beam facility EXCYT at the energy of 30 MeV. The absolute cross-section was measured for CM energy between 13 MeV and 19.5 MeV. The pr

Cette thèse concerne l'étude des noyaux actifs de galaxies (AGN) de faible luminosité dans l'univers proche, principalement peuplé par les "Low Ionization Nuclear Emission-line Regions" (LINERs) galaxies. L'étude a été basée sur un échantillon de LINERls montrant une détection robuste de raie large en émission Halpha, une propriété typique des AGN lumineux de type 1. J'ai étudié le mode d'accrétion et les processus radiatifs de ces LINER 1 s en examinant leurs propriétés en rayons X et multi-Iongueurs d'onde (distribution spectrale d'énergie, SED), et en les comparant t celles des AGN lumineux
