Abstract

Abstract Relative cross sections for the excitation of the 3s, 3p and 3d sublevels of atomic hydrogen were determined in the case of dissociative excitation of H 2, HCl, H 2O, NH 3 and CH 4 molecules by impact of 1000 and 2000 eV electrons. For this purpose the intensity as well as the polarization of the emitted Balmer-α radiation has been measured as a function of an applied homogeneous electric field. Using the theory of the Stark level mixing for H-atoms, it was derived from these data that within the experimental error only the 3s and 3d states of H were excited.
