چکیده

The total absorption spectrometer (TAS) [1] mounted at the GSI on-line mass separator [2] was generally used for measuring β-intensity distributions of nuclei far from stability. Another particularly interesting application is, however, to investigate the structure of individual (low-lying) states of the β-decay parent and daughter nucleus, including isomers. As an example, we present here the results on low-lying Rh levels obtained by studying the decay of 9-s Pd [3]. The Kα(Rh) X-rays and a 54.6-keV γ-ray line, observed in the well-shielded germanium detector of TAS (see Fig. 1), are characterized by a half-life of

Isomerism and Hydrogen Bonding in the Cis-enol Forms of 1-(n-pyridyl)butane-1,3-diones: A Theoretical Study

Molecular structure, isomerism, conformational stability and intramolecular hydrogen bonding (IHB) of cis-enol forms of 1-(n-pyridyl)butane-1,3-diones (nPBD) (n = 2, 3, or 4) have been investigated by means of density functional theory (DFT) calculations. Energy differences for all possible nPBD cis-enol forms of isomers with respect to the most stable form of the correspondin...

The effects of isomerism and side chain mutation on binding energy and NMR/NQR tensors of L-methionylasparagine and L-asparagylmethionine

Density functional theory methods(DFT) and natural bond orbital (NBO) analysis were used to investigate the effects of isomerism and side chain mutation at a microscopic level on the stability, binding energy and NMR/NQR tensors of structural isomers, L- methionylasparagine (Met-Asn) and L- asparagylmethionine (Asn-Met) in the gas phase. The results represented that the isomerism and side chain...
