Classical Newtonian Monte-Carlo Calculation of Ionization of Atomic Hydrogen by Protons in Energy Range 0.05 to 1.0 MeV

Abstract

We have designed a Euler approximation Monte-Carlo code for the calculation of the ionization of atomic hydrogen by protons with energies between 0.05 and 1.0 MeV. This code is used to calculate the total ionization cross sections s(E), the angular distribution double differential cross sections d2s/ (dW - dE) for electrons with energies of 150 eV ionized by 300 keV protons and the energy distribution d2s/ (dW - dE) for the ionized electrons emitted at 10o by protons of energy 300 keV. Our calculations are compared to experimental values of these quantities as well as independent calculations. We find excellent agreement of our calculated cross section and reasonable agreement of our calculated double differential cross section with independent calculations and measurements.
