主　　题：SU3-IBM ^(196)Pt γ-soft-like spectrum 

摘      要：Recently,studies have argued that a spherical-like spectrum emerges in the SU3-IBM,thus creating new approaches to understanding y-softness in realistic *** a previous study,γ-softness with degeneracy of the ground and quasi-y bands was *** this paper,another special point connected to the middle degenerate point is *** is found to be related to the properties of^(196)*** emergentγ-softness is also shown to be important for understanding the prolate-oblate asymmetric shape phase *** low-lying spectra,B(E2)values,and quadrupole moments in^(196)Pt are discussed,and we show that the new model can account for several observed *** is the first part of the discussion on theγ-soft-like spectrum of^(196)Pt.
