Abstract
The present work concentrates on the investigation of various inelastic channels such as positronium (Ps) formation, direct ionization, and total ionization by the positron impact for simple molecules in an extensive energy range (∼Ps formation threshold to 5 keV). The modified form of the well-known spherical complex optical potential formalism and the complex scattering potential-ionization contribution method are used for the calculations. Although only limited literature was available for the molecules studied in the present endeavor, in general, reasonable agreement is found with the existing data. A phenomenological technique developed recently is used in the present work to calculate the Ps formation cross section efficiently.
