Large scale shell-model calculations in the upper part of the sd shell: General description and energy levels for A = 36--39
Results are presented of shell-model calculations for even and odd parity states in nuclei in the mass region A = 36 through A = 39. In the model space used particles in the 2s/sub 1/2/, 1d/sub 3/2/, 1f/sub 7/2/, and 2p/sub 3/2/ shells have been treated as active. The model space was truncated by a new method of diagonal percentage truncation. An effective Hamiltonian was employed, calculated by fitting to the binding energies of a number of reference levels. The calculated level schemes are compared with experimental data and discussed. The calculations yield good agreement with known data. Several fp intruder states are located. On the basis of the calculations several predictions of angular momenta and parity of observed states have been made, as well as predictions of the excitation of not yet observed yrast states.
