Fully vibrationally resolved photoionisation of H2 and D2
Abstract
Cross sections are computed for the photoionization of H2 and D2 molecules in several vibrational states by 584-A radiation, producing ions in a range of vibrational states. Both total cross sections and asymmetry parameters (beta) are determined using the R-matrix method. Good agreement is obtained with recent experiments for the fully vibrationally resolved total cross sections of D2. The beta parameters decrease with vibrational excitation of the targets but also show structure which appears to be associated with Franck-Condon factors.
