By means of a numerical solution of the Boltzmann equation, elastic and inelastic collision cross sections have been derived for electrons in H sub2 and D sub2 subjected to a dc electric field. The steady state distribution function is obtained for electrons initially emitted from a point source into a neutral gas and which subsequently drift under the influence of a uniform dc electric field while undergoing elastic collisions with the gas atoms. Using a method described previously the distribution function of electron energies for electrons in argon and mixtures of hydrogen and argon has been obtained by a mumerical solution of the Boltzmann equation which takes into account elastic and inelastic collisions. Experimental evidence for the existence of compound states in simple atomic and molecular systems is presented. The experimental evidence for these compound states comes from the observation of the elastic and inelastic cross section by electron impact. Author
