Popis: The stopping cross sections of the II–VI semiconductor material ZnSe for 0.4–2.2 MeV 1H, 4He and for 1.6–8.9 MeV 7Li ions have been studied by the Rutherford backscattering technique. The stopping of Zn and Cu for lithium ions were measured by the backscattering and transmission techniques for comparison and reference purposes. The stopping cross sections of ZnSe obtained for hydrogen ions were in good agreement with the semiempirical calculations based on the ZBL-85 model. For helium and lithium ions the stopping cross sections were 4–10% and 1–9% smaller than predicted by the model, respectively. For lithium ions, the stopping cross sections of Zn were systematically 5% below calculations based on the model. The stopping data of Cu agreed well with the literature data.
