THRESHOLD IONIZATION OF HCl BY ELECTRON IMPACT
Journal Article
·
· Journal of Chemical Physics (U.S.)
The ionization of HCl by electron impact was studied in a mass spectrometer with a pseudomonoenergetic electron beam. The ionization potential of HCl was determined as 12.56 plus or minus 0.1 ev. The ionization curve at threshold exhibits excessive curvature which is attributed to the /sup 2/II/sub i/ doublet ground states of the ion estimated to be separated by 0.3 ev. A sharp change in slope of the ionization curve at 1.6 ev above threshold is attributed to the onset of ionization of the A /sup 2/ SIGMA /sup +/ excited state of HCl/ sup +/. (auth)
