(2+1) resonant enhanced multiphoton ionization of H2 via the E,F 1Σ+g state

Abstract

In this paper, we report the results of ab initio calculations of photoelectron angular distributions and vibrational branching ratios for the (2 + 1) REMPI of H 2 via the E,F 1 ~t state, and compare these with the experimental data of Anderson et a!. [Chern. Phys. Lett. 105, 22 ( 1984)]. These results show that the observed non-Franck-Condon behavior is predominantly due to the R dependence of the transition matrix elements, and to a lesser degree to the energy dependence. This work presents the first molecular REMPI study employing a correlated wave function to describe the Rydberg-valence mixing in the resonant intermediate state.

Ultrahigh-density spin-polarized hydrogen isotopes from the photodissociation of hydrogen halides

“…This is essentially gating the detector and reduces amplification of the otherwise very strong H 2+ signal that appears at the center of the image (see figure 4.2). Ion optics were calibrated using previously assigned H + images fr om the 532-nm dissociation of H 2+ in the v=5 and 6 vibrational levels [117].…”
