We consider the one-photon excitation of atomic hydrogen by electron impact in the presence of a homogeneous monochromatic linearly polarized electric field as a model for the radiation field of the laser. In the framework of the approximative approach of Faisal and Rahman (in {ital Fifth} {ital International} {ital Conference} {ital on} {ital Atomic} {ital Physics}, edited by R. Marrus, M. H. Prior, and H. A. Stutgart (University of California, Berkeley, 1976), p. 49), suited for high-energy electrons, we present an analytic expression for the transition amplitude to an arbitrary {ital nlm} state, in terms of hypergeometric Gauss and Appell {ital F}{sub 1} functions, together with the numerical results for excitation to the {ital n}=4 states.
