“…Such a discrepancy can originate only in an erroneous determination of the constituents of equations (2) or (4). Recent measurements of the target pressure have questioned the absolute values of Edwards et al (1988) but the relative values will not change (Edwards et al 1989). In fact, the relative shape agrees with our data.…”

Absolute electron impact cross sections for single ionisation leaving H l in its electronic ground state and double ionisation leading to dissociation into all four constituents have been determined by a direct method in the energy range 0.15-2.6 keV. The values for single ionisation are in perfect agreement with, but the double-ionisation values are much larger than, the earlier determination by Edwards et al. Our results exhibit a close relationship between the H, system and its atomic counterpart, helium, with respect to their response to single-and double-ionisation processes.
