Abstract：
The optimum condition of three commonly used functions in the Genie 2000 γ spectra analysis software have been studied in the 121—1408 keV energy range. The three functions are applied for fitting the full-energy peak efficiency of the HPGe gamma-ray detector. A detailed procedure to obtain the optimum condition is described. The HPGe detector is calibrated at 11 cm by three radioactive sources of point form (¹⁵²Eu, ¹³⁷Cs, ⁶⁰Co) providing 11 energy peaks. After data processing, results shows that the three functions used in the Genie 2000 gamma spectra analysis software fit best at orders 3—5. Lastly the standard radioactive source ¹³³Ba is chosen to validate the results. Differences between the standard activity of ¹³³Ba and the result obtained from the fitting functions are below 1.5%. Therefore the optimum orders of the three functions used in the Genie 2000 γ spectra analysis software are 3—5 with the 11 energy peaks.
