Abstract

The photopeak and escape peak processes were studied in heavy Ce³⁺-doped LuAG and GGAG, Pr³⁺-doped LuAG and undoped BGO scintillating crystals. Energy resolution measurements were performed with 511 keV photons of ²²Na radioisotope. In the pulse-height spectra the escape peaks were resolved clearly on thin samples (up to 3 mm). If sample thickness increases the escape peak cannot be resolved anymore (for thicknesses approx. above 5 mm, especially). Consequently, energy resolution increases by about 40% compared with that measured at 1 mm thick samples.
