AbstractAbstract
[en] In the course of an attempt to obtain an accurate efficiency calibration as a function of energy for a Ge(Li) detector it was found that the relative transition intensities of two commonly used radionuclides 56Co and 66Ga were in error. Further investigations showed the importance of both coincidence and geometrical effects in relative intensity measurements. In complex decay schemes the simultaneous detection of two γ-rays in true coincidence can have a marked influence on the relative intensities deduced unless the source-detector distance is several times the detector radius. Techniques developed for computing these effects for any source-detector distance will be reported and a number of comparisons of theory and experiment will be illustrated. (author)
