摘要：

A microscopic parity-projected calculation, using as intrinsic states the ones obtained in the mean field approach with the Gogny interaction and constraining the octupole moment is carried out for several nuclei in the barium and radium isotope chains. Projected mean values and transition matrix elements are obtained for both, parities as well as for the 0+ - 1- splittings. These quantities are compared to previous results obtained in collective calculations. The differences are discussed and conclusions about the importance of the correlations associated to the projection are extracted.
