PHOTODISSOCIATION OF H2+ AND D2+ - THEORY

Theory is described and calculations made for photodissociation cross section of H2+ (D2+) from each of the ion's 19 (27) vibrational levels. Cross sections are summed over an assumed Franck-Condon distribution of initial vibrational states to give a predicted cross section for comparison with experiment. Auxiliary calculations are made of some of the cross sections using the common δ-function approximation to the continuum radial wave functions, and a comparison made with the results using more exact wave functions shows very good agreement for photodissociation from the lowest vibrational levels, but very poor agreement for photodissociation from higher levels. © 1968 The American Physical Society.
