Untersuchung des Magnesium-27-Zerfalls

Theγ-rays of the decay of Mg²⁷ were investigated with NaJ-crystals, andγ-γ-cascades had been sought for by a fast-slow-coincidence circuit. A method for an exact measuring of the random-coincidence spectrum and a stabilisation method of the multiplier gain is described. The twoγ-lines of 808 keV and 988 keV in coincidence with the 842 keVγ-line and the 817 keVγ-line in coincidence with the 1013 keVγ-line, reported by other authors, could not be observed. If these transitions exist, their intensity would be less than 10^?3 per decay.
