Non-normal parity states in mass 10-15 nuclei

The modified surface delta interaction (MSDI) is used as the effective two-nucleon residual interaction in extensive shell-model calculations for A = 10-15 nuclei; a He-4 core and j-j coupled extra-core nucleon configurations of the form psup(n)sub(3/2)psup(m)sub(1/2)(1dsub(5/2),2ssub(1/2))1 are employed. Level energies and wave functions for low-lying non-normal parity states are first obtained from a simultaneous fit to experimental energies over the entire 10-15 mass range. The wave functions are next tested by comparing predicted nuclear properties with experimental data: single-nucleon spectroscopic factors, beta decay lifetimes, M1 and E2 radiative transition widths as well as E1 and M2 radiative widths are calculated. In general good agreement between experiment and theory is obtained. (orig.)
