Abstract
The rate constant for the collisional deactivation of the H2 continuum in the near uv was measured in pure H2 at low pressures. The continuum emission was excited by 75‐keV electrons and the deactivation rate constant was 1.5 ± 0.2 × 10−10 cm3/sec. An efficiency for excitation of the H2 continuum of 0.11% ± 0.03% was measured at low pressures in the absence of collisional deactivation.Keywords
