| A 40 cc Ge(Li) detector has been used to study the gamma rays emitted in the decay of Cobalt-60, Areenic-74 and Neodymium-147. A system for measuring directional correlations has been constructed with a fast-slow electronics arrangement utilising the Ge(Li) detector and a NaI(Tl) scintillation counter, and the directional correlations of gamma-gamma cascades in Germanium-74 and Promethium-147 have been studied. |
