Description

Experiments have been made to investigate details of the decay of 148Dy and to confirm its nuclidic assignment. Gamma ray yields are presented as a function of bombarding energy for 12C ions incident on 142Nd. The proposed decay scheme is presented, and the 0+ → 1+ beta transition is discussed. In addition, the proposed electron capture decay schemes of 150Dy and 152Dy are given. It is concluded that their beta decays proceed entirely through 1+ states of their respective terbium daughters.
