Abstract

The R-matrix approach is used to calculate the elastic differential, integral, and momentum transfer cross sections for electron impact on H₂CNH within static-exchange-polarization (SEP) and close-coupling (CC) approximations. The electron-impact excitation cross sections from the ground state to the first three low-lying electronic excited states of H₂CNH molecule have been also studied for the first time. A shape resonance of ²A′′ symmetry located at 1.95 eV with a width of 0.56 eV is detected within CC model. The effective collision frequencies over a wide electron temperature range (200−30 000 K) are calculated using the data of the momentum-transfer cross section.
