Abstract:
The available experimental and theoretical cross section data on charge exchange processes in collisions of protons with hydrocarbon molecules have been collected and critically assessed. Using well established scaling relationships for the charge exchange cross sections at low and high collision energies, as well as the known rate coefficients for these reactions in the thermal energy region, a complete cross section database is constructed for proton-C_xH_y charge exchange reactions from thermal energies up to several hundreds keV for all C_xH_y molecules with x=1,2,3 and 1 leq y leq 2x+2. Rate coefficients for these charge exchange reactions have also been calculated in the temperature range from 0.1 eV to 20 ke V.
