Nuclear structure and elastic scattering observables obtained consistently with different NN interactions

Nucleon-nucleon (NN) interactions based on chiral effective theories are commonly used in ab initio calculations of light nuclei. Here we present a study based on three different NN interactions (up to next-to-next-to-leading order) for which structure and elastic proton scattering observables are consistently calculated for 4He, 12C, and 16O. The interactions are compared at the two-body level in terms of Wolfenstein amplitudes, and their predictions for ground-state energies, point-proton radii, and charge form factors, as well as proton elastic scattering observables in the leading-order spectator expansion in the energy range between 65 and 160 MeV projectile energy are presented. To gain further insight into differences visible in elastic scattering observables, we investigate the behavior of the calculated effective nucleon-nucleus interactions for the 12C nucleus based on the different NN interactions.
