Title: Generator-Coordinate Q{sub n}-Q{sub p} Study of Low-Lying Collective States in Neutron-Rich Oxygen Isotopes

Abstract

Beyond mean-field methods based on restoration of symmetries and configuration mixing by the generator coordinate method (GCM) enable to calculate on the same footing correlations in the ground state and the properties of excited states. In this report, we generalize an analysis to allow independent neutron and proton collective dynamics. As an illustration of the method properties of the ground state and first quadrupole state in {sup 20}O are studied.
