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 X 3 B 1 → 1 1 A 1 and X 3 B 1 → 1 1 B 1 excitation cross sections, especially at higher impact energy. Finally, we estimate the accuracy of the 1 1 A 1 and 1 1 B 1 excitation cross sections.
