Nucleon-Nucleus Effective field theory

We build a Nucleon-Nucleus (N-A) effective field theory potential to study A+1 neighbor of an A-body doubly-magic nucleus by attaching a neutron to an inert core with a structure. The low-energy coefficients of the N-A EFT potential are optimized scattering data available for (n,n) process. We use the optimized N-A potential to compute A+1 bound states. We study 5He, 17O and 41Ca nuclei using our approach.
