Abstract
We propose a new method for concentration profile determination using the PIXE technique at different proton energies. The classical deconvo lution process involved is solved by a singular value decomposition of the ill-conditioned matrix obtained by discretization. The mathematic al tool is outlined. Different applications are shown and a comparison with other techniques is presented.
