Shell model calculation for light neutron-rich nuclei

A shell model calculation is carried out for nuclei with 9 less than or equal to A less than or equal to 14 and 3 less than or equal to Z less than or equal to 5. In the calculation, He-8 is treated as core. The data for 24 experimental energy spectra are selected to determine the parameters of the modified surface delta interaction (MSDI) and the single-particle energies. The energy root-mean square deviation is RMS = 0.72 MeV. Then the binding energies, the low-lying excited energy spectra, and the electromagnetic properties are calculated and the results are in good agreement with existing measurements in general. The micromechanism of the halo structure and the parity conversion of the Be-11 are discussed in detail. This work is carried out with the shell model code OXBASH.
