Nonadiabatic corrections to the scattering formalism for the description ofelectron stimulated desorption developed previously are investigated. It turnsout thxt the cross-section for the desorption of ions derived earlier in the Born-Oppenheimer approximation remains essentially unaffected by these corrections(nonadiabatic effects being taken into account with sufficient accuracy in termsof the imaginary part of the BO potential for the ions). The cross-section for thedesorption of reneutralized tons, however, which vanishes in BOA becomesnonzero. In semiclassical approximation the expression for the cross-sectionagrees with the result proposed earlier by Menzel and Gomer. The connectionof the formalism with the Landau-Zener theory of nonadiabatic transitions isbriefly discussed.
