On the excitation of Lyman beta and Balmer alpha radiation by electron-impact dissociation of methaneThe cross sections for the excitation of Ly-beta and H-alpha when methane is dissociated by electron impact have values of 17.1 by 10 to the -19th power sq cm and 26.0 by 10 to the -19th power sq cm, respectively, at an electron impact energy of 100 eV. These results are in disagreement with the implications of recent polarization measurements of H-alpha radiation that suggest negligible H(3p) excitation in the dissociation of CH4 by electron impact.
