The Classical trajectory Monte Carlo Method (CTMC) is applied to the calculation of ionization, excitation, charge transfer and Stopping cross sections in the proton-Hydrogen collision process. Kepler equations for planetary motion are used to resemble the 1s electron in the proton Coulombic field and the electron initial conditions were generated by a microcanonical distribution function. Fixed eccentricities e=0.75, e=0.001 and random ([0,1] range) eccentricities were used for the calculation of cross sections and stopping. The results shows that the e=0.75 y e=random cross sections coincide between them, that is not the case for the e=0.001 distribution; also the total stopping results are in good agreement with the experimental data in the high and intermediate energy range.
