【 摘 要 】

Synopsis Electron impact ionization of the hydrogen molecular ion in the presence of laser radiation is studied theoretically. The kinematical regime of high impact energy and large momentum transfer is considered. The influence of a laser field on the target is taken into account using a quasistatic states model, whereas its effect on the incoming and outgoing electrons is described by the Volkov functions. For the field-dressed target, the molecular bond oscillation factor, extracted from the electron momentum distribution, demonstrates a significantly different behavior compared to the case of the unperturbed target.
