An angular momentum projected particle-hole theory for deformed nuclei and its application to theT=1 negative parity states of20Ne

  • Published:

Abstract

An angular momentum projected particle-hole theory is proposed as an approach to describe excited states of deformed nuclei. Both for the ground and the excited states, angular momentum projections are done before variation. This allows one to look for the effect, with an appropriate constraint, of the difference in the deformations of these states. The theory is applied to the case of Ne20 where the splitting of the giant resonance is observed. Other negative parity states are also studied and their transitions to the 2+ member of the ground state band show interesting features which may have experimental implications. On the other hand, the change in the deformation of the excited states has only a small effect on the transition probabilities.
