beta decay of Cd-127 and excited states in In-127

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