The decay of 124 SB Johnson, John R.

Abstract

The gamma-rays, beta rays and conversion electrons emitted in the beta decay of ¹²⁴Sb →¹²⁴Te have been observed using Ge(Li) and Si(Li) detectors both singly and in coincidence. The measured energies and intensities of the different transitions involved in this decay together with the coincidence results have allowed us to construct the decay scheme. The angular momentum of most of the states and the parity of all of the states of ¹²⁴Te populated in this decay have been deduced, some of them for the first time, and others as confirmations of previous assignments. We have also been able to assign collective parameters to many of these states, in terms of the vibrational model of nuclei, from the reduced branching ratios calculated from the gamma ray intensities.
