“…collision velocity is taken as v = 0.02 a.u.. In these results we find that cross-section first rises as laser intensity is increased from I = 106 W/cm: to I = l0 s W/cm: and beyond it decreases with laser intensity, which is expected physically and is a non-perturbative result also obtained by others [3,15].…”

Abstract.A theoretical study is made of rovibrational excitation of a CO molecule due to proton impact in the presence of an infrared laser beam taken in the electric dipole approximation. Non-perturbative quasi-energy method has been applied to describe laser-molecule interaction. Effect of laser and collision parameters on crosssection is investigated. To show the effect of laser on collision process we have compared our results with field free results.
