摘要：

Rotational excitation of homonuclear diatomic molecules can be simply yet accurately calculated from the scattering parameters of elastic electron-molecule scattering in the fixed-nuclei approximation. The total scattering cross sections for Δj 0 transitions are independent of s-wave parameters, and ratios of Δj=±2 cross sections agree with experimental results in H2 and with rotational close-coupling calculations. Absolute total and differential cross sections can be explained. © 1969 The American Physical Society.
