The lth--partial-wave Coulomb half-off-shell t matrix t/sub l//sup c/(k,q,k/sup 2/) is expressed in terms of hypergeometric functions which are polynomials. The expression is used to compute t/sub l//sup c/(k,q,k/sup 2/) as a function of the off-shell momentum q for two laboratory energies E/sub lab/( = 2k/sup 2/) = 10 and 20 MeV. Results are presented for l = 0 to 10. Our numbers refer to repulsive Coulomb potential encountered in the case of p-p scattering. It is found that in addition to the on-shell discontinuity t/sub l//sup c/(k,q,k/sup 2/) exhibits a singularity as q..-->..0 for higher partial waves.
