· Nucl. Instr. Methods
The photopeak efficiency for gamma rays of energy ranging from 881 kev to 10.88 Mev, for scintillation counters with NaI(Tl) crystala of dimenaions 2" x 2", 3," x 3", and 5" x 4" and a CsI(Tl) crystal of 23/4 x 23/4" was determined. The measurements were carried out with a narrow collimated and a broad parallel gamma beam, using the (n, gamma ) reaction as a gamma source. The effect of the energy of the gamma quanta on the shape of the response function was also measured for the same crystals and energies. (auth)
