Energy loss spectra

Abstract

This paper studies the form of the energy spectrum using a statistical methods study the spectra and to fond expressions for energy loss .This paper study of the spectrum of energy loss of abeam of particles penetrate through of small thickness of different atoms Al, W, Au, Ag, Br and Be and study the different spectrum of the energy loss and the loss of these energies.The energy loss of the spectrum was studied for multi atoms of Al, , W,Au, Ag,Br and Be depending on equation (1) to estimate energy loss for the limited thickness and comparing difference spectrum with difference of atomic numbers .
