Cluster Structures, Halos, Skins, and S-Factors in Fermionic Molecular Dynamics

摘要

Light nuclei are studied in the Fermionic Molecular Dynamics model. No a priori assumptions are made with respect to cluster structure or single-particle energies. The same effective interaction based on the Argonne V18 interaction is used for all nuclei. Short-range central and tensor correlations are treated explicitly using a unitary correlation operator. Calculations of binding energies and radii for Helium and Carbon isotopes are presented. The evolution of cluster structures and halos with increasing neutron number is discussed. The spectrum of 12C is calculated in a multiconfiguration calculation. The molecular structure of the excited states is investigated. The astrophysical S-factors are calculated for the fusion of different Oxygen isotopes.
