Comparison between theory and experiments for the electron emission statistics induced by protons incident on thin carbon foils
Recently, measurements on the statistics of the number of electrons emitted due to MeV light ion impact on solid targets have been fitted adequately by negative binomial distributions. We present here Monte Carlo simulations for backward and forward emissions induced by protons incident on thin carbon foils in the energy range 250 keV -2 MeV, and compare them with experimental results. A general discussion on the statistical distribution of the number of emitted electrons is given. A transport model giving the general form of the probability generating function (pgf) of the distribution of the number of emitted electrons is also proposed.
