G409600100013 The absolute registration efficiency of the detectors G409600100014 was calibrated with a standard set of gamma-ray sourcesG409600100015 22Na, 57Co, 60Co, 109Cd, 133Ba, 137Cs, 151Eu, 241Am. G409600100016 The dead time of the spectrometer did not exceed 5-8% G409600100017 during all measurements. G409600100018 METHOD (GSPEC) G409600100019 INC-SOURCE (BRST) G409600100020 ERR-ANALYS (ERR-T) The total error of relative cumulative yields G409600100021 was estimated considering statistical errors of peak G409600100022 intensity of gamma product lines, analysis of time G409600100023 dependencies, spread of values averaged over G409600100024 individual measurements, and errors of interpolated G409600100025 efficiency values and nuclear physical constants G409600100026 (energy and intensity of gamma lines, half-lives of G409600100027 products). G409600100028 (ERR-S,,5.) The statistical error of measurements of G409600100029 the peak intensity of gamma product lines did not G409600100030 exceed 5%. G409600100031 ADD-RES (COMP) Experimental data are compared with theoretical G409600100032 predictions calculated with TALYS 1.95 and GEF 2021/1.1G409600100033 codes.
