Differential cross sections for the dissociative single and double excitations resulting in H(2p) formation in electron–CH4collisions at 80 eV incident electron energy

Double differential cross sections at six angles ranging from 45° to 143° have been measured for the 12C(e,p)e′ reaction. The proton energy ranged from 15.6 to 17.2 MeV at an incident electron energy of 200 MeV. At the backward angles our results are in good agreement with data reported by Vysotskaya and Afanas'ev but for forward angles the results are lower.

Good Agreement

The differential cross sections for [Formula: see text], n and [Formula: see text], 2n are calculated and compared with some recent data (Caplan and Sealock, manuscript in preparation). The theoretical model in this calculation uses essentially the same approximations as were used by Dressier et al. (1979) for the [Formula: see text] total threshold cross section. The results of this new calculation are in good agreement with the [Formula: see text], n data. However, comparing our results to the [Formula: see text] data at an incident electron energy of 200 MeV and a pion energy of 15 MeV seems to indicate that the [Formula: see text], 2n calculation somewhat overestimates this cross section.

Sum Rule

Tritons resulting from the electrodisintegration of 7Li have been measured at 90° for an incident electron energy of 23.8 MeV over an energy range which ensured that only tritons emitted in the two-body channel were detected. The electrodisintegration cross sections were converted to equivalent photodisintegration data and compared to earlier results. Large discrepancies are observed. It is found that the (γ,3H) channel contributes appreciably to the electric dipole sum rule for 7Li.

Electron Energy Loss Spectra

A set of three computer programs is reported which allow for the deconvolution of overlapping molecular electronic state structure in electron energy-loss spectra, even in highly perturbed systems. This procedure enables extraction of absolute differential cross sections for electron-impact excitation of electronic states of diatomic molecules from electron energy-loss spectra. The first code in the sequence uses the Rydberg–Klein–Rees procedure to generate potential energy curves from spectroscopic constants, and the second calculates Franck–Condon factors by numerical solution of the Schrödinger equation, given the potential energy curves. The third, given these Franck–Condon factors, the previously calculated relevant energies for the vibrational levels of the respective electronic states (relative to the v″ = 0 level of the ground electronic state) and the experimental energy-loss spectra, extracts the differential cross sections for each state. Each program can be run independently, or the three can run in sequence to determine these cross sections from the spectroscopic constants and the experimental energy-loss spectra. The application of these programs to the specific case of electron scattering from nitric oxide (NO) is demonstrated.
