Title: Large-basis no-core shell-model calculations for p-shell nuclei

Abstract

Results of large-basis shell-model calculations for nuclei with A=7-10 are presented. The effective interactions used in the study were derived microscopically from the Reid93 potential and take into account the Coulomb potential as well as the charge dependence of T=1 partial waves. For A=7, a 6({Dirac_h}/2{pi}){omega} model space was used, while for the rest of the studied nuclides, the calculations were performed in a 4({Dirac_h}/2{pi}){omega} model space. It is demonstrated that the shell model combined with microscopic effective interactions derived from modern nucleon-nucleon potentials is capable of providing good agreement with the experimental properties of the ground state as well as with those of the low-lying excited states. In the context of the calculations for A=10 isobars we study in detail the isospin-mixing correction to the {sup 10}C{yields}{sup 10}B Fermi matrix element. (c) 1999 American Institute of Physics.
