Abstract
A finite basis set formed from B-splines is constructed in momentum sp ace for the Schrodinger-Coulomb problem. The pseudospectrum of the bas is set is generated and used to evaluate the Bethe logarithm for groun d-state hydrogen. The method is also used to solve a relativistic vers ion of the Schrodinger equation that cannot be treated in coordinate s pace.
