Abstract
A two-state close-coupling calculation of electron-impact excitation of ethylene to the a approximately 3B1u state (pi --> pi*) is carried out using a version of the Schwinger multichannel method developed for distributed-memory parallel computers. The calculated integral cross section shows a sharp rise at threshold, in agreement with available experimental data. The integral and differential cross sections are useful in understanding the mechanism of this excitation process and indicate the possible presence of a core-excited shape resonance near thresholdKeywords
