GAUSS .9. AN INTERACTIVE PROGRAM FOR THE ANALYSIS OF GAMMA-RAY SPECTRA FROM GE SEMICONDUCTOR-DETECTORS

The newest member of a series of computer programs developed at the IN EL for analysis of gamma-ray spectra from Ge semiconductor detectors i s GAUSS IX. This program makes use of the computational routines of GA USS VII in an interactive structure. The interactive features are impl emented with OSF/Motif and the X Window System. This interactive versi on can dramatically decrease the turnaround time for spectral analyses , especially when the user needs to refit some of the peaks with speci ally-chosen fitting parameters. The graphic features increase the oppo rtunity for detecting pat terns and anomalies in the spectral analyses . The user of this program can set up the analysis parameters (i.e., p eaks, peak regions, etc.) interactively via window dialogs. The user c an interactively display and review the results, selectively re-fit pe aks, and save or purge the results, as appropriate. The spectral displ ays can include the spectral data, peak locations, peak fitting region s, fit curves, and background curves; and the display is completely zo omable, scrollable, and resizable.
