S. Baccaro et al., PRECISE DETERMINATION OF THE LIGHT YIELD OF SCINTILLATING CRYSTALS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 385(1), 1997, pp. 69-73
A method to determine the photopeak position of the gamma absorption s
pectrum of radioactive sources in low light yield scintillators as lea
d tungstate is discussed. The method is based on the parametrization o
f both the Compton and photoelectric contributions to the spectrum and
it is proven to be reliable and to give stable and precise results.
