Shell model calculations on natural parity states in 10≦ A≦14 nuclei

Abstract

Shell model calculations of natural parity states in the 10≦A≦14 mass region have been performed by assuming an inert4He core with the residual interaction in the 1p shell only. The modified surface delta interaction (MSDI) has been used as an effective two-body interaction. The MSDI parameters as well as the single-particle binding energies have been deduced from a least-squares fit to experimentally known levels in, firstly, the seperate10B,11B-C,12C,13C-N and14N nuclei, and secondly, the whole mass region 10≦A≦14. Multipole moments for ground states and M1 and E2 radiative widths for excited states have been calculated with the resultant wave functions.
