ResumenThe generalized coherent state model, proposed previously for a unified description of magnetic and electric collective properties of nuclear systems, is used to study the ground-state band charge density as well as the E0 transitions from 0+β to 0+g. The influence of the nuclear deformation and of angular momentum projection on the charge density is investigated. The monopole transition amplitude has been calculated for ten nuclei. The results are compared with some previous theoretical studies and with the available experimental data. Our results concerning angular momentum projection are consistent with those of previous microscopic calculations for the ground-state density. The calculations for the E0 transitions agree quite well with the experimental data. Issues like how the shape transitions or shape coexistence are reflected in the ρ(E0) behavior are also addressed.
