Abstract
The angular momentum projected generator coordinate method, with the axially symmetric quadrupole moment as generating coordinate, has been applied to study the shape coexistence and quadrupole collectivity in the neutron-deficient isotopes . The finite range and density dependent Gogny interaction, with the parametrization , has been used in the calculations. A good qualitative agreement with the available experimental results is found. Our results indicate that remains, on the average, as a magic proton number for the considered nuclei and also support the experimental evidences for rotational bands built on coexisting low-lying states of oblate and prolate shapes.
