| Abstract | ||
| 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. | ||
