Abstract

The decay scheme Tb152→ Gd152 has been investigated with sources prepared in an isotope separator. In addition to obtaining γ-ray and conversion electron spectra, γ-γ and e-γ coincidence measurements were carried out. A disintegration scheme has been established that includes all transitions in Gd152 reported in earlier Eu152 β-decay studies. In addition, four new transitions which establish two excited levels in Gd152 were observed. One of these is a 0+ state at 1047 keV and the other, at 929 keV, has probably spin 2+. The 0+ state decays with two monopole transitions to lower 0+ states, and the transition from the 929 keV level to the 344 keV first excited level, seems to contain a considerable E0 admixture. The two new levels are tentatively interpreted as members of a three-phonon quintet.
