Section Analysis

The results of electron drift and diffusion measurements in parahydrogen have been analysed to determine the cross sections for momentum transfer and for rotational and vibrational excitation. The limited number of possible excitation processes in parahydrogen and the wide separation of the thresholds for these processes make it possible to determine uniquely the J = 0 → 2 rotational cross section from threshold to 0.3 eV. In addition, the momentum transfer cross section has been determined for energies less than 2 eV and it is shown that, near threshold, a vibrational cross section compatible with the data must lie within relatively narrow limits. The problems of uniqueness and accuracy inherent in the swarm method of cross section analysis are discussed. The present results are compared with other recent theoretical and experimental determinations; the agreement with the most recent calculations of Henry and Lane is excellent.

This is an addendum to a previous paper (Bui and Stauffer, to be referred to as I). The explicit formulae which are not given in I for the case of electron–sodium atom scattering are given in this addendum. Tables of all appreciable partial waves with L ≤ 10 are presented for various values of the energy of the incident electron up to 4 eV. Results for the total elastic cross sections are compared with the most recent variational calculations of Sinfailam and Nesbet.

Resonant Electron Capture

The cross-section for resonant electron capture in oxygen has been measured by means of a Lozier apparatus. The value obtained, 2∙25 ± 0∙3 x 10 -18 cm 2 at 6∙7 eV, has been employed to calculate the attachment cross-sections to be expected at various mean energies in electron swarm conditions, assuming a Maxwellian distribution of velocities, and it has been shown that all previous attachment coefficient values are compatible with the resonant capture. Reasons have been advanced for doubting the accuracy of the Tate & Smith values of positive-ion cross-sections at lower electron energies.

Scattering Cross Sections

Electron penetration in semi-infinite Au for normal and oblique angles of incidence at energies between 0.5 and 4 keV is simulated within a Monte-Carlo frame work. The elastic scattering cross sections have been obtained from a modified Rutherford differential cross section, whereas inelastic core and valence electron excitation are calculated using the Gryzinski's expression. The dependence of the backscattering coefficient, mean implantation depth and stopping profiles on the angle of incidence has been examined. These quantities are found to be significantly enhanced as the angle of incidence becomes higher which is generally in consistent with previous simulations.
