Abstract
The Pauli rearrangement potential given by the second-order diagram is evaluated for a nucleon optical model potential (OMP) with matrices of the nucleon-nucleon interaction in chiral effective field theory. The results obtained in nuclear matter are applied for in a local-density approximation. The repulsive effect is of the order of 5–10 MeV at the normal density. The density dependence indicates that the real part of the microscopic OMP becomes shallower in a central region, but is barely affected in a surface area. This improves the overall resemblance of the microscopic OMP to the empirical one.
