• CHx radicals
• Cross sections

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 15-500eV 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 so
