The effect of angular momentum and parity projection on the energy and deformation of the oblate and prolate minimum in /sup 28/Si has been studied. We discuss the approximations resulting from variation without, before, and after projection for a number of standard nucleon-nucleon interactions. We find that the intrinsic oblate and prolate minimum occur in reversed energetical order for most forces. The effect of angular momentum projection alone tends to resolve the discrepancy but this effect is reduced if the projected states are allowed to vary.
