Polarization effects on the two-photon dissociation of HD+ with two radiation fields in the presence of one and two intermediate resonant states.

Abstract

The polarization dependence of resonant two-photon dissociation characteristics has been investigated for ${\mathrm{HD}}^{+}$ excited from the ground state by two fields of different frequencies. The change in dissociation probability with field intensity and the dissociation line shape have been shown in the case of a single intermediate resonance for all possible combinations of polarizations. The photofragment energy spectra and the branching ratio between two possible continuum-energy states have been investigated for these polarization states when two intermediate resonances are present.
