Abstract:
Excited states in Gd-160 were populated via beta decay from the low- and high-spin isomers in Eu-160. The highspin, K-pi = 5(-) state feeds several two-quasiparticle levels, as well as a sequence associated with a. vibration and a K-pi = 4(+), hexadecapole vibrational structure. The decay scheme was significantly improved with the observation of new transitions and states when compared with the two competing level schemes from over four decades ago. Configuration assignments for some of the multiquasiparticle levels have been suggested, based upon decay properties, systematics from neighboring nuclei, and comparisons with theoretical calculations. In addition, 15 new low-spin states and approximately 60 new transitions were observed resulting from the decay of the low-spin Eu-160 isomer.
