چکیده انگلیسی
A complete scan of the detector over a 0.5Â cm step grid was performed for three positions of the 1Â cm x 1Â cm window. For each configuration the energy spectrum was measured and the peak centroid, the FWHM, the area and peak asymmetry of the 662Â keV gamma transition were analyzed. The data show that, even in a 3” thick LaBr3:Ce crystal with diffusive surfaces the position of the full energy peak centroid depends on the source position. We verified that, on average, the position of the full energy peak centroids measured in the three 1Â cm x 1Â cm window configurations is sufficient for the correct identification of the collimated gamma source position.
