TOTAL CROSS-SECTIONS OF ELECTRON COLLISIONS WITH S-ATOMS - H2S, OCS AND SO2 MOLECULES (E-I-GREATER-THAN-OR-EQUAL-TO-50-EV)

Collisions of intermediate to high energy electrons are considered wit h S-atoms as well as H2S, OCS and SO2 molecules as targets. We employ e(-)-atom total cross sections calculated in the complex optical poten tial, to calculate e(-)-molecule total cross sections in a simple and a modified Additivity Rule. Our total (elastic + inelastic) cross sect ions above 50 eV, fare reasonably well as compared to various experime ntal and theoretical data. The calculated inelastic cross sections ser ve as the upper limit of total ionization cross sections. Results are presented graphically from about 10 to 5000 eV.
