Gamma Decay Hindrance Factors Used in Systematic Configuration Assignments

AbstractA simple empirical relation is proposed to correlate theK-hindrance factor with the number of quasiparticles in the state configuration. The reduced hindrance\({{F}_{\nu }}\) =\({{({{t_{{1/2}}^{\gamma }} \mathord{\left/ {\vphantom {{t_{{1/2}}^{\gamma }} {t_{{1/2}}^{w}}}} \right. \kern-0em} {t_{{1/2}}^{w}}})}^{{1/\nu }}}\) has been empirically modified such that\(\nu \) =\(\Delta K - L - ({{N}_{\pi }} - {{N}_{\nu }})\), instead of\(\nu \) =\(\Delta K - {\kern 1pt} \,L{\kern 1pt} \), where\({{N}_{\nu }}\) and\({{N}_{\pi }}\) are the numbers of neutron and proton quasiparticles in the state configuration. In systematics, the modified hindrance factor can be used to uniquely determine theK-isomer state configuration.
