Investigation the Nuclear stopping and Straggling of Swift heavy Ions Using Thomas- Fermi Potential

Abstract

In the present work we has been proposed an equation depends on unclear differential stopping cross section to evaluate the nuclear straggling of energy loss for uranium ion interacts with aluminum 13A26 and gold 79Au197 nuclei. The equation is connection between nuclear straggling with energy and atomic number of heavy swift ion. The present theoretical model for this work considers the nucleus of target atom as stationary state besides the ion-nucleus potential is Thomas-Fermi potential which applied with different values of α. The results which obtained for straggling of energy loss of uranium in the high density target (Gold: Au) and low density target (Aluminum: Al) were in agreement with previous studies. The basic equations have been written in Fortran-90 using CVF6.6 for executing the program.
