Abstract:

Background: Strong octupole correlations are observed in mass region giving rise to a number of isomeric states decaying via type of transition involving interacting orbitals. Theoretically, the and neutron orbitals or the and proton orbitals are predicted to be involved in these enhanced decays. Purpose: This work reports on the systematics of reduced transition probabilities and configurations of octupole isomers in order to compare them based on their structures such as even-even, even-odd, odd-even and odd-odd.  Methods: The data for a total of isomers is collected from the ENS

Abstract:

In this work, the difference between pH-induced isomerization and urea-induced unfolding, and the urea- and thermal-induced unfolding processes in different isomeric forms of Bovine serum albumin (BSA) are studied experimentally. Our results show that urea-induced unfolding is a two-step, three-state transition in both the N-form and the B-form, but a single-step, two-state transition in both the E-form and the F-form. At the same time, thermal-induced unfolding shows a two-state transition in all isomeric forms, but the cooperativity of unfolding is different.

Abstract:

This study covers the analysis of isomeric forms of nitrophthalic acids with pyridine. This work dwells on the complementary experimental (X-ray, IR and Raman) and theoretical (Car-Parrinello Molecular Dynamics (CPMD) and Density Functional Theory (DFT)) studies of the obtained complexes. The conducted studies showed that steric repulsion between the nitro group in ortho-position and the carboxyl group causes significant isomeric changes. Modeling of the nitrophthalic acid—pyridine complex yielded a short strong intramolecular hydrogen bond (SSHB). The transition energy from the isomeric form

Three metal atoms form a wide variability of frameworks: M3 triangular, dicapped M3 triangular, V shaped M3, M3 linear, five-, six- and seven- metallocycles and unique structures of which triangular and linear are the most common.

The trimeric cluster ions are readily generated by electrospray ionization (ESI) or sonic spray ionization (SSI).

Abstract:

The structural properties of the very neutron deficient systems around N~Z~40 have been studied in two experiments performed at the GANIL and Legnaro laboratories. The fragmentation of a 60 MeV/u92 Mo beam on a natural nickel target at the GANIL Laboratory, France, produced exotic nuclei along the proton drip line in the mass 80 region. Isomeric decays have been observed for the first time in the N=Z+2 systems 74 36Kr, 80 39Y and 84 41Nb. The isomer in 74 Kr is interpreted as the hindered decay from an excited 0+ state, supporting the long-standing prediction of prolate/oblate shape coexistenc

Basically one starts with the same two fragments and they are connected in different way to build the two isomers. Later, the energies involved i

The chapter explains the Markovnikov's rule wherein the alkene and adduct are unsymmetrical. This is something which two isomers could form.

One aspect of making a gamma-ray laser concerns the rapid re lease of energy stored in a long-lived nuclear isomer. A proposed method for the release of this energy is to pump the isomerto a nearby, shorter-lived nuclear excited state. This excited state subsequently decays to a lasing transition. In this paper, we consider the dynamical coupling of the nucleon and electron motion using classical dynamics and calculate the perturbation on the spectra.

Abstract:

Besides the usual thermal assisted poling procedure the photoassisted poling reported for polymers containing azobenzene chromophores is of current interest. Usually the enhanced orientational mobility under illumination with visible light in the absorption band of the chromophore is explained by the trans⇔cis isomerization cycle of the azo dye, with a photoisomerization trans⇒cis and a thermal relaxation cis⇒trans. Because of the more compact shape of the cis isomer the rotational mobility is much higher than that of the trans isomer, thus polar orientation under electric DC field is possible

Abstract:

In the two-step pumping scheme for a gamma-ray laser, the most uncertain step is that of exciting the nucleus from a long-lived storage isomer to a nearby short-lived state that then decays to the upper lasing level. For a crystalline structure host, the radiation inducing this interlevel transfer step must be used efficiently so as not to destroy the crystal. High-intensity sources of photons are available only for relatively low quantum energy, but it is difficult to couple a long-wavelength photon directly to the very small nucleus.
