Abstract
The total and differential cross sections for individual rotational and vibrational transitions in the photoionisation of the H2 molecule by 584 AA radiation are calculated in the static-exchange approximation with the addition of the adiabatic dipole polarisation potential. Further, it is demonstrated that the measurement of the relative intensities of the Q and S rotational branches for the transition to the nu 'th vibrational state of H2+ at two angles determine the vibrationally resolved asymmetry parameter beta nu '. The value of beta nu ', obtained from the data of Ruf et al (1983), is 1.87 for nu '=0, and agrees with the calculated value 1.89.Keywords
