Study Stopping Power Collision in one of Nuclear Element

Abstract

The retarding force of the charged particles when interacts with matter causing loss of particle energy, this physical phenomenon in nuclear physics called stopping power. it has a lot of important applications such as in nuclear medicine and privation effects of radiations. The charge particles are alpha and beta particles. in this paper we studies the stopping power, collision and the stopping power of radioactivity of nuclear elements and to find the relationship between stopping power collision and stopping power of radioactivity, with arrange of CSDA range for the low energy electrons data of element F. the CSDA range he CSDA range it is an average distant length of the moving charge particles when it is path slows to stop. By using approximation of CSDA range we can calculate the rate of the loss in the energy at any point along the path of the travel by assuming these energies loss at points of the track are equal to whole stopping power loss. The CSDA range can be found by reciprocal integration of the total stopping power. from the Figures (3),(4),(5) and(6)we can get good results
