Abstract
Energy levels and transition rates are calculated for 28Si and 32S in the framework of the particle-hole model. Transitions between excited states as well as transitions to and from the ground state are considered. Particular attention is given to the low-lying energy levels and to the J π = 1 − states in the giant resonance regions of the two nuclei. A finite-range force is employed in the residual interaction. A spherical basis set is used in constructing the secular matrix and is limited to 0ħω and 1ħω excitations. Reasonable agreement is obtained for the positions of energy levels and many of the transition rates. Corrections to previous work in the literature on 28Si giant resonance calculations are also presented.
