Abstract:

The decay properties of the neutron deficient nuclei $ sp{144}$Gd, $ sp{142}$Gd, $ sp{ rm 141g}$Gd, $ sp{ rm 141m}$Gd and $ sp{140}$Gd are investigated in detail for the first time and the new beta decaying isomers $ sp{ rm 141g,m}$Gd, $ sp{141}$Tb(A) and $ sp{140}$Gd are discovered. A gas-jet recoil-transport system and a conversion electron spectrometer are designed and constructed in order to measure the electromagnetic transitions emitted following their decay. Levels schemes are deduced for the daughter nuclei $ sp{144}$Eu, $ sp{142}$Eu, $ sp{141}$Eu, $ sp{140}$Eu, and $ sp{141}$Gd and sp

Abstract:

The buildup of the cosmogenic nuclides ³He and ²¹Ne in surficial rocks permit exposure ages and erosion rates to be estimated. This dissertation extends the cosmogenic exposure technique to garnets, plagioclase with significant nonspallation ²¹Ne components, and alluvial fill terraces. Garnets from Nanga Parbat, Pakistan have low nucleogenic ³He and moderate radiogenic ⁴He concentrations. ³He exposure ages from garnets in glacial erratics indicate glacial advances at Nanga Parbat at about 16 ka and 55 ka. 3He in alluvial garnets suggests that denudation in small unglaciated basins proceeds 5 t

Molecular states in 8B, 10B, 11B, 11C and 12C, have been studied in the reactions 6Li+12C at 60MeV 10B+ 12C and at 84.5 MeV. Final states in these nuclides were kinematically recon structed from the measured energies and angles of the charged decay products. The original motivation was to identify theoretically predicted, but so far unobserved, three-centre molecular states in 8B. No evidence for these was found. However, the 7Be+p decay of low energy 8B states was observed. The decays of the nuclides with mass 10, 11 and 12 via d and ? emission allowed the study of two-centre and three-centre

This thesis considers the use of two U-series nuclides – 231 Pa and 230 Th – as proxies for studying ocean circulation.

Measurement by MC-ICP-MS of 10 litre water samples is possible for samples with as little as 4 and 2 fg of 231 Pa and 230 Th and yields typical uncertainties of 6% and 14% respectively.

Abstract:

With only two ingredients, atomic nuclei exhibit a rich structure depending on the ordering of the different proton- and neutron-occupied states. This ordering can give rise to excited states with exceptionally long half-lives, also known as isomers, especially near shell closures. On-line mass spectrometry can often be compromised by the existence of such states that may even be produced in higher proportion than the ground state.

Abstract:

The partition of radionuclides between solid and solution phase has been studied in humic/quartz sand ternary systems. Data have been recorded under ambient (air) and inert (O2 and CO2 free) atmospheres. For Eu (III) and Th (IV), the systems show simple ternary behaviour, with sorption decreasing (and mobility increasing) in the presence of humic, whilst for U (VI), the behaviour is more complex, with the humic enhancing sorption and reducing mobility. There is also evidence that the sorbed humic has an enhanced affinity for the uranyl, which is probably due to fractionation of the humic. Furt

Constraining past episodes of climate change and glacial response is critical for understanding future impacts of climate change, especially in the high latitudes where warming is expected to be rapid and most of Earth's glaciers exist. Many studies of past glacier size utilize rare isotopes called cosmogenic nuclides to perform surface exposure dating. Since most areas of Earth's surface that were previously glaciated were covered by erosive ice, which stripped away pre-existing cosmogenic nuclides, surface exposure dating yields the timing of the most recent deglaciation.

Abstract:

Nuclear magnetic resonance (NMR) spectroscopy has proven to be an invaluable tool for the modern chemist, despite being a relatively insensitive spectroscopic technique. However, it is precisely this insensitivity that limits characterization of low-receptivity nuclides, which make up the bulk of transition metal nuclides, in particular. In this work, high-fields were used to collect the first 61Ni solid-state NMR (SSNMR) spectra of diamagnetic nickel compounds, specifically, bis(1,5-cyclooctadiene)nickel(0) (Ni(cod)2), tetrakis(triphenylphosphite)nickel(0) (Ni[P(OPh)3]4), and tetrakis(triphen

Abstract:

In den Hochgebirgen Asiens bedecken Gletscher eine Fläche von ungefähr 115,000 km² und ergeben damit, neben Grönland und der Antarktis, eine der größten Eisakkumulationen der Erde. Die Sensibilität der Gletscher gegenüber Klimaschwankungen macht sie zu wertvollen paläoklimatischen Archiven in Hochgebirgen, aber gleichzeitig auch anfällig gegenüber rezenter und zukünftiger globaler Erwärmung. Dies kann vor allem in dicht besiedelten Gebieten Süd-, Ost- und Zentralasiens zu großen Problem führen, in denen Gletscher- und Schnee-Schmelzwässer eine wichtige Ressource für Landwirtschaft und Stromerz

Abstract:

Terrestrial cosmogenic nuclides such as beryllium-10 have recently been used as a way to determine basin-average erosion rates around the world. These erosion rates are useful to geomorphologists investigating landscape evolution. The Hangay Mountains in Mongolia are a prime location to use beryllium-10 because of the granitic rocks that provide the quartz needed for cosmogenic analysis as well as the lack of observed evidence of recent or old mass wasting events that mobilize sediment and bedrock with much lower cosmogenic concentrations that cause underestimations of erosion rates.
