Box, 11001 Belgrade, Yugoslavia A new method is proposed to investigate the photoionization of atoms in parallel electric and magnetic fields. A combination of the complex coordinate method, a discrete variable representation (DVR) and a variant of the Lanczos iterative procedure is used to obtain the complete photoabsorption spectrum in a single calculation.
