Abstract

The off‐shell Jost functions are studied for a potential which is the sum of the Coulomb potential and an arbitrary local short‐range central potential. We derive their singular on‐shell behavior and their connection with the pure Coulomb off‐shell Jost functions. For the latter we derive a large variety of interesting explicit analytic expressions which are useful for various purposes.
