SISS-92:a computer code for the simulation of ion-surface scattering

A new and efficient computer code for the simulation of ion scattering experiments is presented. Results of simulations with this code are compared to experimental data as well as existing simulation results from the literature. Within a simulation, it is possible to investigate separately the influence of thermal vibrations and the divergence of the primary ion beam. It is shown, that the broadening of the peaks in an angular-dependent intensity profile is mostly due to imperfections in the ion source and detector.
