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 .
