Abstract

Shell model calculations using the effective interaction approach of Talmi are reported for normal parity states in nuclei of mass number 6–9. To fit simultaneously the energies of levels in these nuclei, energy shifts of ground state rotational bands in 8Be and 9Be are introduced. These shifts have their origin in the deformations of nuclei. The obtained matrix elements fit the data better than those of earlier authors, and resemble the matrix elements obtained from realistic interactions such as the Hamada-Johnston potential. Theoretical predictions are compared with new experimental data. M1 radiative widths, log ft values, and spectroscopic factors for single- and two-nucleon transfers are given to help in the interpretation of new data. The need for carrying out more calculations for 1p shell nuclei with realistic forces is discussed.
