Analysis of γ γ directional correlation data taken with a multi-detector system

When performed with a multi-detector system, γ γ directional correlation measurements need to be corrected differently for each independent detector pair, especially when those detectors have different active volumes and subtend different solid angles with respect to the radioactive source. We show here a method, which is suitable for setups containing dissimilar detectors. Successful tests were made for four γ γ cascades, from Co 60 , Ba 133 and Eu 152 .
