Abstract

We derive general expressions for the Jost function of a nonlocal central potential in any angular momentum state, and generalize these results when there is a tensor component in the nonlocal potential. These results relate the Jost function to the Fredholm determinants and are generalizations of the Jost–Pais theorem for the corresponding local case.
