Elastic scattering observables using realistic NN-interactions for Carbon 12

The study of atomic nuclei depends on nuclear reactions to extract both reaction- and structure-related observables. With the development of new realistic nucleon-nucleon interactions, derived from chiral effective field theory, used in an ab initio no-core shell model (NCSM) we can calculate one-body nuclear densities and scattering observables of carbon isotopes. For the elastic scattering of protons and neutrons from nuclei, a microscopic optical potential is derived with the Watson expansion of the multiple scattering series. This spectator expansion allows for the use of the same nucleon-nucleon (NN) interaction when calculating the one-body densities, which must be folded with the NN scattering amplitudes. We present the dependence of scattering observables in the 65-100 MeV range for Carbon 12 on the NN interaction.
