Experimental and theoretical determination of the stopping power of ZrO2 films for protons and α-particles

Abstract

We report the results of an experimental-theoretical study on the stopping power of ZrO2 films for swift H and He ion beams. The experiments, using the Rutherford Backscattering technique, were done for protons with incident energies in the range 200–1500 keV and for a-particle beams with energies in the range 160–3000 keV. The theoretical calculations were done in the framework of the dielectric formalism using the MELF-GOS model to account for the ZrO2 target electronic response. It is shown that for both ion beams, the agreement between theory and experiment is quite remarkable.
