Title: A new way of assignment of concentrations in pixe analysis
Abstract: A new method of assignment of element concentrations in trace-element analysis is proposed. The concentrations in thin samples (t<2 mg/cm2) are determined by measuring the characteristic X-ray yield and the sample-mass derived from the energy-loss of the beam while passing a thin target. It is shown that the energy-loss is accurately determined by the γ-yield of the 1013 keV γ-radiation of the 27Al(p, p′γ)27Al reaction induced by a 3.0 MeV proton-beam in an Al-beam stop behind the target. This feature has been confirmed experimentally with targets of various thicknesses using a 3.0 MeV proton beam of mm2 dimensions. First results of the use of a proton microbeam are presented and discussed.
