β Decay of ¹²⁷Cd and Excited States in ¹²⁷In

Summary, in English

A dedicated spectroscopic study of the β decay of ¹²⁷Cd was conducted at the IGISOL facility at the University of Jyväskylä. Following high-resolution mass separation in a Penning trap, β-γ-γ coincidences were used to considerably extend the decay scheme of ¹²⁷In. The β-decaying 3/2⁺ and 11/2^- states in ¹²⁷Cd have been identified with the ¹²⁷Cd 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 β feeding to excited states of ¹²⁷In and the decay scheme of ¹²⁷In are discussed in conjunction with large-scale shell-model calculations.
