摘要：

Backscattering spectra for 2-MeV He ions incident on single-crystal GaP at small angles to the 〈110〉 axis, parallel to the {110} plane, have been studied. For symmetric tilts 0.6° ≤ |θ|≤ 2°, pronounced asymmetry in a complex structure of the spectra is observed. The spectra normalized to the random yield have been reproduced by a Monte Carlo simulation. Thermal vibration amplitudes found previously for the 〈100〉 axis have been used. The effects of beam angular divergence and ion-atom potential are studied in detail. Consequences for lattice location applications are discussed. © 1990.
