Resumen:
We present a theoretical and experimental research on the the energy loss (stopping power andstraggling) of H and He ions in zinc oxide [1]. The measurements were carried out at the fa-cility of the Instituto de F´ısica da Universidade Federal do Rio Grande do Sul, in Brazil, usingthe Rutherford Backscattering technique for (300-2000) keV H ions and (300-5000) keV Heions. The theoretical research was encouraged considering the molecular description of ZnOas crystal solid using the density functional theory. The energy loss calculations for H and Heions with different charge states were performed with the shelwise local plasma approxima-tion (SLPA). The equilibrium charge state of He inside ZnO is analyzed based on the presentstopping measurements, and a semiempirical charge state distribution is proposed.
