Electron-Impact study of S2molecule using theR-Matrix method

We have employed the R -matrix method [1] to compute elastic (integrated and differential cross section DCS), momentum-transfer and excitation and ionization cross sections for electron impact on S 2 molecule. We have calculated DCS, in correlated one-state model, by using the POLYDCS program of Sanna and Gianturco [2]. The data of momentum-transfer cross section, generated from DCS, is used to compute effective collision frequencies [3] over a wide electron temperature range (200-30000 K). The ionization cross sections are calculated in the binary-encounter Bethe (BEB) model [4] and compared with [5, 6].
