Abstract:

PPA Photo-Peak Analysis is a simple FORTRAN computer code, that fits photo-peaks in pulse-height gammaray scintillation spectra, and gives results in terms that are immediately useful to the gamma-ray spectroscopist. PPA fits experimental data with a Gaussian Normal distribution function, containing a linear bias term through the use of an iterative, least-squares technique. As many as five photo-peaks can be fitted by PPA in any given experimental spectrum with the following results 1 the exact channel location of the photo-peak 2 the width of the photo-peak FWHM 3 the peak count rate 4 the integrated photo-peak count rate and 5 the integrated photo-peak count rate corrected for radioactive decay to zero-time. The mathematics involved in the analysis, the input data required, and the results of some experimental measurements, as well as some typical applications of the code are discussed. In addition, a complete FORTRAN listing with flow diagrams is given. Author
