β decay of Cd 127 and excited states in In 127

A dedicated spectroscopic study of the $\ensuremath{\beta}$ decay of $^{127}\mathrm{Cd}$ was conducted at the IGISOL facility at the University of Jyv\"askyl\"a. Following high-resolution mass separation in a Penning trap, $\ensuremath{\beta}\text{\ensuremath{-}}\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ coincidences were used to considerably extend the decay scheme of $^{127}\mathrm{In}$. The $\ensuremath{\beta}$-decaying $3/{2}^{+}$ and $11/{2}^{\ensuremath{-}}$ states in $^{127}\mathrm{Cd}$ have been identified with the $^{127}\mathrm{Cd}$ ground state and the 283-keV isomer. Their respective half-lives have been measured to $0.45{(}_{8}^{12})\phantom{\rule{0.16em}{0ex}}\mathrm{s}$ and 0.36(4) s. The experimentally observed $\ensuremath{\beta}$ feeding to excited states of $^{127}\mathrm{In}$ and the decay scheme of $^{127}\mathrm{In}$ are discussed in conjunction with large-scale shell-model calculations.
