Abstract

We present exact closed analytic expressions for (i) the partial-wave projected off-shell Coulomb T matrix, (ii) the Coulomb Jost state, and (iii) the off-shell T matrix associated with the sum of the Coulomb potential and simple separable potentials, for all partial waves in the momentum representation. These expressions consist of combinations of elementary functions and the extensively studied hypergeometric function 2 F 1(1, i γ; 1+i γ) and are therefore suitable for numerical computations.
