Theoretical total cross sections fore-SO2scattering over a wide energy range (0.1−2000 eV) revealing a 3.4-eV shape resonance

Abstract

We have used the ab initio R-matrix formalism at low impact energies (below the ionization threshold of the target) and the spherical complex optical potential methodology above the ionization threshold to generate total cross sections for e-SO 2 scattering over the energy range from 0.1 to 2000 eV. The eigenphase diagram and total cross section indicate a structure at 3.4 eV which is ascribed to a shape resonance, evidence for which appears in earlier experimental studies.

“…With the amalgamation of these two formalisms we are able to predict the total cross sections over a wide energy range. [55][56][57][58] The numerical results of the total cross sections for C 4 H 4 S are reported from 0.01 eV to 5000 eV as listed in Table 3 and are also plotted graphically (Fig. 10).…”
