Utilizing Binary theory to investigate dependent of Impact parameteron energy loss of swift ions.

Binary stopping theory has been used to describe the electronic stopping of swift heavy ions in matter. It is a widening of Bohr’s classical theory of 1913 incorporating screening, higher-order-Z1 and shell corrections, high-speed quantum and relativity corrections as well as projectile excitation and ionization .Calculated stopping parameters depend on ion charge. Equilibrium stopping forces may be computed by adoption of a suitable model for the equilibrium charge state. A numerical calculation have been done to estimate the energy loss of an incident swift ions on an atomic target as a function of the impact parameter between the moving nuclei. In present work a theoretical study of the stopping cross sectionis done onH-ion interaction with Al and Ne by writing a program (TT0.f90) was written in Fortran-90 using software Compaq visual Fortran 6.6 (CVF) for compiling, linking and exacting the program. Good agreement a achieved with previous works.
