Low-energy electron collisions with thioformaldehyde

The elastic integral, differential, and momentum transfer cross sections and the excitation cross sections from the ground state to the first three low-lying electron excited states for low-energy (0-10 eV) electron collisions with thioformaldehyde (H2CS) molecule are calculated using the R-matrix method. Eighteen target states are included in the close-coupling formalism. Three core-excited shape resonant states (2B2,2B1,2A1) and three Feshbach resonant states (2B2,2A1,2B1) are determined for the (N + 1)-electron H2CS- system in the low-energy range. The dissociative electron attachment processes at the first two low-lying core-excited shape resonant states are proven by performing a series of scattering calculations, indicating the S-(2P) yields together with the CH2 fragment at three different states.
