LASER-INDUCED-RESONANCE CALCULATIONS FOR THE PHOTODISSOCIATION OF H2+ IN AN ADIABATIC ELECTRONIC-FIELD REPRESENTATION USING THE RADIATION-FIELD GAUGE

The properties of the laser-induced first resonance state in the photodissociation of H-2+ are obtained from calculations in the radiation-field (RF) gauge, also called the velocity gauge, as a function of intensity and wavelength of the field within an adiabatic electronic-field representation, and the results are compared to the corresponding ones obtained using a diabatic RF gauge representation and an adiabatic electric-field gauge representation. Gauge transformation within the coupled equations used for these calculations is also discussed.
