Shell-model calculations in the sd shell. I. Energy spectra

Abstract

Shell-model calculations have been performed for a number of nuclei in the sd shell to obtain binding energies and energy spectra. The realistic interactions of Kuo (1967), and Elliott et al (1968), and the empirically determined matrix elements of Preedom and Wildenthal (1972) were used in the full sd shell basis. Comparison with experiment shows that the Preedom-Wildenthal interaction works well in the lower part of the shell, whereas the other two give rise to shifts of whole rotational bands in most nuclei.
