In order to check the performance of the spectrometric method, the spectrometer was tested on the gamma energy spectrum of a Bi-207 radioisotope. The method presented here was successful on the improvement of the energy resolution of the spectrometer.en10.1080/10739140701540297info:eu-repo/semantics/closedAccessgamma raysBa-133energy spectrumtiming methodenergy resolutionNaI(T1) scintillation detectorArticle355537541WOS:000249842100006Q3
