Abstract

We present elastic cross sections for electron interactions with arsine (AsH3) in gas phase over an extensive energy range from 0.5 to 5000 eV by combining two computational methods. The ab initio R-matrix method is employed for low-energy computations up to 15 eV and the intermediate to high-energy calculations were performed using the spherical complex optical potential (SCOP) method. The elastic cross section computed through the R matrix and SCOP formalism shows consistency at crossover energy (11–12 eV) and gives reasonable accord with the available data. Besides elastic cross sections, the differential cross section at low and intermediate incident electron energies is reported. The electronic excitation cross section is also reported at low energies. Shape resonance is observed at around 2.4 eV due to the formation of a transient negative ion state.
