High spin spectroscopy and shape evolution inCd105

Abstract

High spin states in 105Cd were studied using ,!M o(l60 , 2pn),0SCd reaction at an incident beam energy of 75 MeV. The level scheme of l05Cd has been observed up to J n = (47/2") and excitation energy ~10.8 MeV with the addition of 30 new y 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.

Microscopic nuclear structure models and methods: chiral symmetry, wobbling motion andγ–bands

“…In this class of models, the triaxial projected shell model (TPSM) approach has been demonstrated to correlate the high-spin data of well deformed and transitional data with remarkable success [13]. The purpose of the present work is to provide an overview of the recent applications of the TPSM approach to a wide range of nuclear properties [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. We also report new results on the observation of γ-bands based on excited configurations.…”
