Scientific paper

The potential-energy and transition-dipole-moment (TDM) measurements of Green et al. (1974, 1976) are used to calculate the partial photodissociation cross sections of HeH(+) as functions of wavelength. The results are presented in graphs and tables for vibrational levels 0-5 and rotational level 1 of the transitions from the X1Sigma+ ground state to the A1Sigma+, B1Sigma+, and C1Pi excited states: perturbations in the gradual increase of the successive maxima are associated with TDM peaks at internuclear distances 2.0, 2.4, and 2.1 au, respectively. Implications of these determinations for stellar-atmosphere and H II region models, gas-discharge lasers, isotope separation, polarized-atom production, and the study of photochemical reactions are indicated.
