K-X-Ray-γ directional correlations in the decay of54Mn,65Zn,75Se,85Sr,133Ba and207Bi
K-X-ray-γ directional correlations following the decay of54Mn,65Zn,75Se,85Sr,133Ba and207Bi have been performed. The experimental set-up consisted of a set of four scintillation counters, one for detecting X-rays and the three others for detecting γ-rays, placed at 90°, 180° and 270° with respect to...
