摘要：

A new two-target-atom model for calculating the intensity of particles that have been directly recoiled from a surface has been developed to examine the effects of shadowing and blocking on the recoils. This model is similar to one that was recently introduced for calculating the intensity of the primary particles scattered back from a surface. Important surface structure information can be obtained by comparing calculated recoil intensities as a function of incident ion identity and kinetic energy, target orientation, and recoil angle and energy to experimentally measured quantities.
