REX: A Computer Program for PIXE Spectrum Resolution of Aerosols

Kaufmann, Henry C; Akselsson, Roland LU and Courtney, William J (1976) In Advances in X-Ray Analysis 19. p.355-366
Abstract
REX is a Fortran program for analysis of spectra obtained in PIXE analysis. The underlying model is still under development; however, one year of experience has demonstrated REX’s capability to be a fast reliable tool. The modeling of the different components and effects of the physical model is briefly discussed. Evidence is shown that secondary effects mostly due to Compton-scattering in and around the detector are important factors. In order to assure that heavy elements are recorded with sufficient sensitivity during short bombardment times, low energy X-rays are suppressed but not completely absorbed by use of a Mylar absorber with a hole. Such an absorber sometimes introduces severe problems for other techniques of spectrum analysis.... (More)
