The photoelectron (PE) angular distribution for the resonant two-photon autoionization of H/sub 2/ through the lowest autoionizing state of /sup 1/..sigma../sub g/(1sigma/sub u//sup 2/) symmetry has been studied. It is found that at low laser intensities the spontaneous decay of the intermediate resonant state (different vibrational levels of the B/sup 1/..sigma../sub u/ state) can modify the PE angular distribution significantly, whereas at higher intensities, this effect is washed out by the other intensity-dependent competing channels.
