Application of the scaled quasi-free scattering model absorption potential to electron scattering by CHx (x = 1, 2, 3,4)

In this work, the newly derived scaling quasi-free scattering model (SQFSM) absorption potential is applied to electron-CHx (x = 1-4) collisions in the intermediate energy range. More specifically, elastic differential, integral, grand-total (elastic plus inelastic), and total absorption cross sections are reported in the 15-500 eV energy range. A complex optical potential composed of static, exchange, correlation-polarization, and our absorption potential contributions is used to represent the electron-molecule interaction dynamics, whereas the iterative Schwinger variational method combined with the distorted-wave approximation is used to solve the scattering equations. The comparison between our calculated results and the existing experimental and theoretical data in the literature is encouraging.
