Half-lives and emission probabilities of delayed neutron precursorsAg121−124

Half-lives and delayed neutron emission probabilities have been measured for ${}_{}{}^{121-123}{}_{}{}^{}\mathrm{Ag}$. The new isotope ${}_{}{}^{124}{}_{}{}^{}\mathrm{Ag}$ has been identified by its delayed neutron decay. Its half-life is 0.54±0.08 s and its neutron emission probability is > 0.1%. From beta decay measurements, a half-life of 2.07±0.03 s was found at mass 123 and assigned to the previously unknown ${}_{}{}^{123}{}_{}{}^{}\mathrm{Cd}$. An improved half-life for ${}_{}{}^{124}{}_{}{}^{}\mathrm{Cd}$ of 1.2±0.1 s is reported.
