CH molecules at low and high energy range

In this communication, studies of the total ionization cross sections of hy- drocarbon molecules (CH, C2H2) due to electron impact are presented. Electron im- pact ionization cross sections (EIICS) have been calculated from threshold ionization energy to high energy (10 MeV). Apart from EIICS calculation the values of collisional parameters are also calculated. The theoretical model, developed by Khare, has been modified to calculate the total ionization cross section for molecules. Obtained theoret- ical cross sections are compared extensively with a number of experimental and theo- retical data. The obtained values of collisional parameter compared with the available experimental values.
