Abstract The performance of the integral-bias summing coincidence spectrometer (the sum-peak spetrometer) in measurements of directional correlations of gamma rays has been tested. As compared with the conventional method, the sum-peak spectrometer is easier to use and seems to yield results which agree with those obtained with the ordinary method. Because of the complex shapes of response functions of gamma rays above about 3 MeV, the new method is best suited to the study of cascading transitions below this energy, where the two methods appear to complement each other. The analysis of the sum-peak spectra in the present work is based on a simple graphical method which seems to yield satisfactory results; the use of a computer method is suggested. Some previously unknown directional correlation functions of gamma-ray cascades in 106 Pd and 118 Sn are also reported.
