AbInitio Computation of Charge Densities for Sn and Xe Isotopes.

Abstract

We present the first abinitio calculations for open-shell nuclei past the tin isotopic line, focusing on Xe isotopes as well as doubly magic Sn isotopes. We show that, even for moderately hard interactions, it is possible to obtain meaningful predictions and that the NNLO_{sat} chiral interaction predicts radii and charge density distributions close to the experiment. We then make a new prediction for ^{100}Sn. This paves the way for abinitio studies of exotic charge density distributions at the limit of the present abinitio mass domain, where experimental data is becoming available. The present study closes the gap between the largest isotopes reachable by abinitio methods and the smallest exotic nuclei accessible to electron scattering experiments.
