Study on nuclear isomers in odd-even 67-79As, 71-83Br, and 83-89Rb isotopes
Study on nuclear isomers is one of the way to understand the structure of certain nucleus. The odd-even 67-79As, 79-83Br and 83-89Rb isomers excited around 68Ni had been confirmed as sub-shell closure based on the research conducted by Broda and his group in 1995.

Study on nuclear isomers is one of the way to understand the structure of certain nucleus. The odd-even 67-79As, 79-83Br and 83-89Rb isomers excited around 68Ni had been confirmed as sub-shell closure based on the research conducted by Broda and his group in 1995. The odd-even 67-79As, 79-83Br and 83-89Rb were selected in this work to investigate the theoretical isomerism of nuclei. The odd-even populated nuclei of 67-79As, 79-83Br, and 83-89Rb were considered in this work by using Deep-Inelastic Collisions reaction of 76Ge (635MeV) + 198Pt. The theoretical calculations were carried out to investigate the characteristics of isomeric level, magnetic reduced transition probabilities B(M2), binding energy (B.E), mean-lifetime (τ) width of isomeric level (Γγ), hindrance factor (Fw), fragments energy (PLF) and Coulomb barrier for the isotopes.
