Abstract
A general approach to high energy elastic scattering of ions on atoms is presented. Differential cross sections for the scattering of particles with similar masses are obtained in analytical form. The cross sections are doubly-differential (i. e. with respect to the scattering angle and to the energy transferred during the collision) and were obtained by using the binary encounter approximation and assuming an inverse-power r-s central force potential for interaction between the colliding particles. Numerical calculations are performed for H+ - H+ and H+ - H (1s) collisions and the results are compared with quantum mechanical calculations and experimental data. The cross sections are a good approximation for the ion-atom systems with impact energies greater than 1 keV.
