Abstract
A computational method is suggested to analyze gamma ray peak position data of a series of closely shifted spectra of Ir-192 measured by a HPGe spectr ometer and an iteration program, Recovery-98 has been designed to find the fine curve of the spectrometer nonlinearity for energy calibration. The pro gram is applied to check a previous experiment (measuring the gamma energie s of Sr-85, etc.), and the revised result has been reported. (C) 1999 Elsev ier Science B.V. All rights reserved.
