Title: Electron-impact excitation of the a-italic /sup 3/. sigma. /sub g//sup +/, B-italic /sup 1/. sigma. /sub u//sup +/, c-italic /sup 3/Pi/sub u/, and C-italic /sup 1/Pi/sub u/ states of H/sub 2/

Normalized differential and integral cross sections for electron-impact excitation of the dipole-allowed B-italic /sup 1/..sigma../sub u//sup +/,C-italic /sup 1/Pi/sub u/ and dipole-forbidden a-italic /sup 3/..sigma../sub g//sup +/,c-italic /sup 3/Pi/sub u/ states of molecular hydrogen have been determined by analysis of energy-loss spectra obtained with a crossed-beam apparatus at electron-impact energies of 20, 30, 40, and 60 eV and scattering angles ranging from 10/sup 0/ to 120/sup 0/. Normalization of the data was achieved by utilizing the elastic differential cross sections measured previously by us (preceding article). The cross sections are compared with other available theoretical and experimental data.
