Electron Impact Cross Sections Applicable to Molecular Lasers.

Abstract

In the program on excited molecules we have completed the experiments on dissociative attachment from vibrationally excited HCl and HF. In this work we observed an unusually large cross section (10 to the -14th power sq cm.) for Cl-/HCl (v=2) and proposed a new mechanism for dissociative attachment by electron impact. These results have been published in Journal of Chemical Physics, 1981. In the program on electronic excitation of noble-gas atoms we have established the experimental methods for studies up to the threshold region. The first results have been obtained for the n=2 states of He, within 4 eV of threshold. In the 2 3S and 2 3P cross sections we observed anomalous angular dependences attributable to a new 2P resonance.
