Non-Rutherford 160° Backscattering Cross Sections of 0.70-2.48 MeV Protons on Fluorine and Magnesium

Differential elastic 160° backscattering cross sections of 0.70-2.48 MeV protons on fluorine and magnesium were measured by relative measuring method. The analysis proton beams were provided by 2×1.7 MV accelerator at Beijing Normal University. The resonance backscattering cross sections of F and Mg were presented in graphical forms, which should be useful for the sensitive analysis of new thin-film materials with F and Mg.
