Dissociative ionization of H₂by 400 eV circularly polarized photons

Abstract

Calculations of single photon one-electron ionization-dissociation of H 2 are performed ab initio with accurate quantum mechanical description of the nuclear motion. The clear interference pattern is observed in the photoelectron angular distribution detected in the molecular frame. An effect of this interference on the dissociation process is found.

“…There seems to be an unignorable rotation p rec /p rep ≈ 0.22 rad to the molecular axis for the case of α ∼ π/2. By taking the recoil momentum into account, we treat the nuclear motion quantum mechanically within the Born-Oppenheimer approximation [17]. However, we do not find significant differences in the results from the models with and without consideration of the recoil momentum.…”
