Structure of even-even nuclei using a mapped collective Hamiltonian and the D1S Gogny interaction

Understand

A systematic study of low energy nuclear structure at normal deformation is carried out using the Hartree-Fock-Bogoliubov theory extended by the Generator Coordinate Method and mapped onto a 5-dimensional collective quadrupole Hamiltonian.

• Results obtained with the Gogny D1S interaction are presented from dripline to dripline for even-even nuclei with proton numbers Z=10 to Z=110 and neutron numbers N less than 200.
• The properties calculated for the ground states are their charge radii, 2-particle separation energies, correlation energies, and the intrinsic quadrupole shape parameters.
• For the excited spectroscopy, the observables calculated are the excitation energies and quadrupole as well as monopole transition matrix elements.
