Estimation of the total energy loss and continuous slowing down range (CSDA) of positrons in carbon and silver

Abstract

In this paper we calculate the total stopping power (collision and radiative) for positrons within the range of energies (0.02 – 50) MeV for two elements (carbon and silver), also we calculate continuous slowing down range (CSDA) for the same elements by using P. Bal etal. formula in the energy range (5-1000) MeV. The results were compared with the data of ICRU which shows a good agreement.
