“…de Heer [79] that the electronic excitation cross sections are the same for H 2 and its isotopomers, although there may be some difference when processes such as dissociation are involved. There is a very important consistency check, which requires that any cross sections obtained experimentally when substituted into the electron Boltzmann equation should result in calculated transport and excitation coefficients.…”

The demand for electron-impact cross sections has increased tremendously in recent years. There is, however, a special interest in such cross sections for hydrogen molecules and its isotopomers, HD and D 2 , because of their presence in tokamak edge plasmas, planetary atmospheres and at different astrophysical sites. This explains the need for having well validated sets of electron-impact cross sections for different processes. This work reviews the electron-scattering cross sections for elastic and inelastic processes at different electron energies for both these molecules. The elastic momentum transfer cross sections and inelastic cross sections for electron-impact rotational, vibrational and electronic excitation, emission, dissociation, ionization and dissociative electron attachment have been evaluated and well validated in this work wherever and whenever possible.

“…Geiger and Schmoranzer (1969) also studied the vibration population distribution in the Lyman and Werner bands systems of H 2 , D 2 and HD with the electron energy loss method. The dissociative excitation of H 2 and D 2 by electron impact and isotope effects in the resultant atomic Lyman and Balmer emissions (De Heer 1981, Vroom and De Heer 1969, Karolis and Harting 1978, Ciocca et al 1997 have been reported. The ionization and autoionization of D 2 have also been studied (Landau et al 1982, Pichou et al 1983, Hall and Andrić 1984, Čadež et al 1988.…”

The high-resolution (full width at half maximum = 0.11 Å) emission spectrum of the deuterium molecule produced by electron-impact excitation at 100 eV has been measured in the wavelength range 1200 - 1660 Å. In conjunction with the experimental measurement, transition probabilities of and D band systems are calculated. Synthetic spectra based on the calculated transition probabilities are in very good agreement with the optically thin experimental spectra. While centrifugal effects on the overall Lyman band emission intensity in D2 and H2 are similar, the effect of rotation-vibrational perturbations between the B 1u+ and C 1u+ states on spectral intensities is found to be less significant in D2. Excitations via isotropic ( J = 0) and anisotropic ( J = ±2, and 0) interactions for the dipole forbidden E, F 1g+-X 1g+ transition are inferred from the measured spectra. Excitation cross sections of the B 1u+-X 1g+ and C 1u-X 1g+ bands, along with the estimated E, F 1g+-B 1u+ cascade cross section, for D2 are obtained.
