Vibrationally and rotationally resolved cross sections and angular distributions of photoelectrons from H2

Vibrationally and rotationally resolved cross sections and asymmetry parameters for the photoionisation of H2 by 584 and 304 AA radiation are studied for the vibrational states of H2+ from 0 to 12 (14 for the 304 AA line). Vibrationally summed cross sections ( sigma ) and vibrationally averaged asymmetry parameters ( beta ) are evaluated from these results. The calculated ( sigma ) agrees well with the experimental data. The values of ( beta ) are 1.93 and 1.86 for the 584 AA and 304 AA lines, respectively.
