Characterization of nuclear physics targets using Rutherford   backscattering and particle induced x-ray emission
  Rutherford backscattering and particle induced x-ray emission have been utilized to precisely characterize targets used in nuclear fission experiments. The method allows for a fast and non destructive determination of target thickness, homogeneity and element composition.
