Analytical and empirical study of the energy lost to alpha radiation infunction atomic number Z of the target

In this work, we recorded the alpha spectra of radium-226 and amrecium-241 sources using a semiconductor detector and Rutherford scattering chamber. We also measured the energy loss of alpha particles in gold foil (target) and in aluminum foil as a function of alpha energy and as a function atomic number Z of the target. Comparison between experimental and theoretical results show a good agreemen.
