Abstract

Neutron-rich Mo107 has been reinvestigated by analyzing the large statistics γγγ and γγγγ coincidence data from the spontaneous fission of Cf252 at the Gammasphere detector array. Two new bands have been identified. The potential-energy surface calculations of this nucleus have been performed. The calculations show evidence for the 5/2+[413] configuration of the ground-state band and 7/2[523] configuration for the 348-keV excited band, as assigned in previous work. The two bands newly established are proposed to be one- and two-phonon γ-vibrational bands built on the 7/2[523] Nilsson orbital, respectively, in the current paper. Triaxial projected shell-model (TPSM) calculations have been performed to explain the level structure and are found in fair agreement with experimental data. In particular, the TPSM study confirms the γ- and γγ-vibrational structure for the two observed excited band structures. Systematics of the one- and two-phonon γ-vibrational bands in the A100 Mo series is also discussed.
