State-resolved Photodissociation and Radiative Association Data for the Molecular Hydrogen Ion

Abstract

We present state-resolved (electronic, vibrational, and rotational) cross sections and rate coefficients for the photodissociation (PD) of H 2 + and radiative association (RA) of H-H +. We developed a fully quantum mechanical approach within the nonrelativistic Born-Oppenheimer approximation to describe H 2 + and calculate the data for transitions between the ground electronic state 1s g s and the 2p u s ,

BEAMDB and MOLD—Databases at the Serbian Virtual Observatory for Collisional and Radiative Processes

“…MolD as a part of SerVO and VAMDC is intensively used by astrophysicists for model atmosphere calculations of solar and near solar-type stars, atmospheric parameter determinations, etc. as well as for theoretical and laboratory plasma research [71][72][73][74][75][76]. Such data are also important for astrochemistry and especially for studies of early Universe chemistry (see e.g., Heathcote et al [74]).…”

Laser-driven production of the antihydrogen molecular ion

“…We note that contrary to Ref. [56] here the total RA cross sections are calculated via an explicit sum over nuclear spin-averaged rovibrational transitions [55].…”

“…The H + 2 RA process has been studied for H in the ground state [53][54][55], and for the H(2s) state above an effective (assumed equilibrium) temperature of T > 10 K [56]. Here we calculate the RA process via excited states for H(n ≤ 3) down to T = 1 mK, noting that the formulation of the γ-H − 2 system is identical to that for γ-H + 2 .…”

Semiclassical Treatment of High-Lying Electronic States of H2+

“…Many calculations for energies and wave functions of H 2 + have been performed, one before quantum mechanics was invented . Some have involved simplified models, , whereas others utilize the separability of H 2 + in spheroidal coordinates to obtain accurate, almost exact results (see, e.g., refs − and the references therein).…”
