Abstract

On the basis of the Hartree-Fock-Bogoliubov (HFB) plus quasiparticle random phase approximation method (QRPA) based on the Green's function approach with Skyrme force, we discuss the anomalous E2 properties of the first 2+ states in neutron-rich nuclei 32Mg and 30Ne. The B(E2) values and the excitation energies of the first 2+ states are well described within HFB plus QRPA calculations with spherical symmetry. We conclude that pairing effects account largely for the anomalously large B(E2) values and the low excitation energies in 32Mg and 30Ne.
