Abstract

The collective hamiltonian for the quadrupole surface vibrations has been calculated microscopically for the Fe, Ni and Zn isotopes using axially symmetric deformed Hartree-Bogoliubov states which are evaluated with the Gogny force and quadrupole constraint. The microscopic wave function of the correlated ground state is described as a linear superposition of the wave functions of the deformed Hartree-Bogoliubov basis with a weight given by the ground state solution of the collective Schrödinger equation. This correlated ground state is then used to evaluate the isotopic differences of the charge density and the rms radii. The results are compared with experimental data from electron scattering.
