Abstract
A new method is described for performing solid-angle corrections on gamma angular correlation data. The gamma scanning technique was applied to two wrap-around Ge(Li) detectors in order to map their intrinsic photopeak efficiencies as functions of the energy and direction of incidence. A collimated 152Eu radioactive source of 1 mCi was used in the mapping procedure. Concerning directional correlations, no numerical integration is necessary for each gamma cascade measured, because a different correlation function is proposed for the fitting, where the angle-dependent effects to be corrected have been factorized. Only few energy interpolations are needed, in order to obtain the correction coefficients present in the new function. Tests were performed with the 4 → 2 → 0 cascade of 60Ni, and 0′ → 2 → 0 and 2′ → 2 → 0 of 100Ru, showing good agreement with previous results.
