Surface Delta-Interaction in Nucleon-Pair Shell Model

The effect of surface delta-interaction (SDI) in nucleon-pair shell model truncated to an SD-subspace isstudied. The results show that with the single-particle level splitting fully taken into account, for realistic SDI strength,the surface delta-interaction also enhance the E2 and M1 transitions of low-lying states.
