Abstract

A microscopic angular momentum projection after variation is used to describe quadrupole collectivity in (^30,32,34Mg) and (^32,34,36,38Si). The Hartree-Fock-Bogoliubov states obtained in the quadrupole constrained mean field approach are taken as intrinsic states for the projection. Excitation energies of the first (2⁺) states and the (B(E2,0⁺→ 2⁺)) transition probabilities are given. A reasonable agreement with available experimental data is obtained. It is also shown that the mean field picture of those nuclei is strongly modified by the projection.
