Precision energy measurements of high energy gamma rays occuring in the decays of 46Sc, 82Br, 99Mo and 110Agm

Abstract

Curved-crystal spectrometers have been utilized to determine the energies of 21 gamma rays following the decays of 46Sc(T4x = 83.8 d), 82Br(7"1 = 35.4 h), 99Mo(T~ = 66.6 h) and 11°Agm(Tl = 25.3 d). Seventeen of these gamma rays have energies in the range between 550 keV and 1121 keV and thus provide a number of calibration standards which supplement the earlier standards published by Raeslde and others.
