  • High spin states in neutron-rich 116,118,120Cd nuclei have been investigated by observing high-fold prompt γ-ray coincidence events from the spontaneous fission of 252Cf with the Gammasphere detector array. The yrast bands have been extended with spin up to 18h in118Cd and 16h in 116,120Cd respectively. The band structures are calculated using the cranked shell model and possible origination for the backbends in the yrast bands is discussed. Proposed 5－ and 7－ levels are observed in each of these cadmium isotopes, and possible explanation for the negative states is discussed based on systematic comparison. A quasi-rotational band based on 7－ level in 118Cd has been established.

Abstract: High spin states in neutron-rich 116,118,120Cd nuclei have been investigated by observing high-fold prompt γ-ray coincidence events from the spontaneous fission of 252Cf with the Gammasphere detector array. The yrast bands have been extended with spin up to 18h in118Cd and 16h in 116,120Cd respectively. The band structures are calculated using the cranked shell model and possible origination for the backbends in the yrast bands is discussed. Proposed 5－ and 7－ levels are observed in each of these cadmium isotopes, and possible explanation for the negative states is discussed based on systematic comparison. A quasi-rotational band based on 7－ level in 118Cd has been established.
