Abstract

Using particle induced prompt photon spectrometry, PIPPS, the ratios of deceleration values of charged particles in samples and standards can be used to determine elemental compositions. Through the spiking of samples and standards with a compound containing a known amount of a non-analyte element (lithium), to which a relative decelaration value is ascribed, appropriate relative deceleration values for samples and standards can be assessed by measuring the prompt γ-ray yields induced in the spike. Using 5 MeV protons this method was tested for the determination of chromium in a selection of reference standards using pure compounds of chromium as analyte standards. The application of both the average cross section as well as the average stopping power approaches were investigated.
