The Hartree- Fock (HF) minima for the nucleus /sup 28/Si were obtained for the prolate, oblate, and spherical shapes by using the interaction obtained by Preedom and Wildenthal. The interaction gives rise to large energy separation between the prolate and the oblate shapes. The spherical solution is just 2 MeV above the lowest HF (oblate) minimum. The spectrum projected from the oblate HF state is in good agreement with the experimental spectrum. The transition probabilities for the different energy levels also agree reasonably well. The configuration-mixing calculations performed on the basis of states projected from the three shapes indicate that there is no signiflcart mixing of different projected states. The sccond 0+2 state thus obtained corresponds to the third 0+3 state in the experimental spectrum, and stems dominantly from the spherical HF state. It is seen that the structure of the energy levels of /sup 28/Si, especially the second 0+3 level, is very sensttive to the two-body interaction. The results are compared with those obtained using the renormalized interaction of Kuo. (1 figure, 2
