Considering interactions and scattering of positrons with argon (Ar) and krypton (Kr) atoms, we have calculated total cross-sections (QT = Qel + Qinel ) using complex spherical potentials for these systems. In positron–atom scattering it is difficult to bifurcate the ionization and cumulative excitation contained in the total inelastic cross-section. An approximate method called CSP-ic (complex...
. In this paper we report our calculations on several important total cross-sections (TCSs) of positron impact on isoelectronic N2 and CO molecules, treated in the complex spherical potential formalism. Basically the total (complete) cross-section QT consists of elastic and inelastic contributions. Our total inelastic cross-section (Qinel) contains ionization and electronic excitations together...
