Abstract
We consider the effect of a low-frequency electromagnetic field on the spectra of electron emission in energetic nonrelativistic ion-atom collisions. The field is assumed to have linear polarization and to be weak compared to the typical atomic field. The incorporation of the projectile interaction opens a new scenario to the combined study of electromagnetic and atomic interactions. Our work suggests that the electromagnetic field can have a profound effect on two of the most important structures that appear in the electron emission spectra: the electron capture into the continuum and binary encounter (BE) peaks. We show that in the BE peak region the result for the laser-assisted scattering depends on the theory applied for the collision part, the first Born approximation or the distorted wave Born approximation.
