Abstract
Synopsis
We reported elastic and excitation cross sections for electron collisions with methylene radical using R-matrix method for electron energies ranging from 0.01 to 15 eV in close-coupling (CC) approximation. We discuss the multi-channel-coupling effects on the calculated cross sections and resonances, and how the number of excited states included in the target state impacts the convergence of the elastic and the X3B1 → 11A1 and X3B1 → 11B1 excitation cross sections, especially at higher impact energy. Finally, we estimate the accuracy of the 11A1and 11B1 excitation cross sections.
