Abstract
The absorption cross section of H2 has been measured in the region between 77.5 and 82.4 nm and the effects of electric fields up to 22 kV/cm on the cross sections have been investigated. The apparent cross section is found to be increased in the neighborhood of optically allowed transitions to npσΣu1+ and npπΠu1 states with n=4−7. This increase in absorption is attributed to field mixing with nearby optically forbidden states.Keywords
