High Spin Spectroscopy and Shape Evolution in 105Cd

High spin states in Cd-105 were studied using Mo-92(O-16, 2pn)Cd-105 reaction at an incident beam energy of 75 MeV. The level scheme of 105Cd has been observed up to J(pi) = (47/2(-)) and excitation energy similar to 10.8MeV with the addition of 30 new gamma transitions to the previous work. Spin and parity for most of the reported levels are assigned from the directional correlation orientation (DCO) ratios and linear polarization measurements. The microscopic origin of the investigated band structures is discussed in the context of triaxial projected shell model (TPSM). The energies of observed positive-and negative-parity bands agree with the predictions of the TPSM by considering triaxial deformation for the observed excited band structures. The shape evolution with increasing angular momentum is explained in the framework of cranked shell model (CSM) and the total Routhian surface (TRS) calculations.
