Popis:	We propose and implement a spectral approach to describe continuum states of diatomic systems. The method is based on Generalized Sturmian Functions in prolate spheroidal coordinates. With the one-electron dihydrogen cation as an example, we demonstrate the numerical efficiency by calculating photoionization cross sections.
