Dispersive optical model calculations for neutron rich nuclei

Nuclear structure and nuclear reactions represent different energy domains, and it is clear that the two are correlated as nuclear scattering cannot be fully understood without a precise description of the nucleus itself.

A consistent approach, presented in this work as the dispersive optical model (DOM), was employed to describe nuclear properties above and below the Fermi energy. Using experimental data and structure information available to constrain the parameters, it has been successfully implemented for 40Ca and 48Ca.

Recently, the DOM was used to extrapolate calculations to heavier Ca isotopes, to clarify how nuclear properties evolve as one goes from stability to the drip lines. Preliminary results show agreement with expected trends and encourage further predictions for neutron rich nuclei.

Also, an analysis of pertinent ground state properties was carried out to investigate asymmetry effects on nucleon densities, generating an alternative energy density profile consistent with rms radii data and particle numbers.
