Properties of heavy nuclei from configuration mixing of symmetry-restored
self-consistent mean-field states
Self-consistent mean-field methods have become a standard tool to
describe and analyze the properties of all nuclei throughout the chart
of nuclei but the lightest ones. They provide the only currently
available fully microscopic model that can be applied to all heavy
nuclei, using the full model space of occupied states and using
the same effective interaction for all nuclei. Typical observables
that can be described are masses, radii, or deformations. In this
talk I will give reasons why and present a method how to go systematically
beyond the mean-field approach by adding long-range correlations
through symmetry restoration and configuration mixing. Doing so
improves the modeling of all typical mean-field observables, and gives
access to collective excitations, their excitation energies, and
transition moments. I will focus on ground-state correlations and
discuss their implications on the global systematics of binding energies,
deformations, and strategies to adjust effective interactions.
