Determination of the cascade summation coefficients of gamma quanta for a semiconductor detector in the 59–2754 keV range

A method of measuring the cascade summation coefficients of a semiconductor Ge(Li)-detector with a relative efficiency of 15% without using calculation programs is proposed. An uncertainty of 2% (k = 2) in the cascade summation coefficients obtained for energies of 59–2754 keV is obtained. A method of constructing the overall efficiency curve of the detector up to an energy of 2754 keV using ⁶⁰Co, ⁸⁸Y, and ²⁴Na radionuclides is proposed. The measured cascade summation coefficients are compared with those calculated using the ETNA program (LNHB, France). __________ Translated from Izmeritel’naya Tekhnika, No. 9, pp. 58–62, September, 2006.
