Possible very anharmonic one- and two-phonon γ-vibrational bands in 103Mo
2017
High-spin levels of 103Mo have been reinvestigated by analyzing the high statistics γ-γ-γ and γ-γ-γ-γ coincidence data from the spontaneous fission of 252Cf taken with the Gammasphere detector array. Two bands and 30 new transitions have been identified. A potential energy surface calculation has been performed. The calculation confirmed the 3/2+[411] configuration of the ground state band and 5/2−[532] for the 346keV excited band, as assigned in the previous work. The two newly established bands were proposed to be one- and two-phonon γ vibrational bands coupling to the 5/2−[532] Nilsson orbital, respectively. Triaxial projected shell model calculations have been applied to explain the level structure and are found in good agreement with experimental data.
