Investigated the beta decay from Indium-101 to Cadmium-101.
Assigned new I-beta and logft values for the decay process.
Compared results with large-scale shell-model calculations.
Confirmed the allowed beta decay characteristics of Cadmium-101.
Validated previous spin-parity level assignments based on decay feeding arguments.

Abstract

This work reports on new experimental information regarding the beta decay In-101 -> Cd-101, obtained with the DESPEC set-up within the FAIR Phase-0 campaign in the year 2021. A first tentative assignment of I-beta and logft values is provided. The results are compared to large-scale shell-model calculations confirming the picture of allowed decays. The spin-parity of the added levels, assigned in previous fusion-evaporation experiments, is confirmed on the basis of decay feeding arguments.
