Zusammenfassung
The correlation betweenβ-particles and circular polarizedγ-radiation was measured for the J→Jβ −-transition Ar41–K41. Gaseous sources were used. A correlation coefficientA=(+0,33±0,07) was found. From this, a ratio of Gamow-Teller to Fermi matrix elementM G /M F =+2,3 +0,9−1,3 and a Fermi matrix element MF= 0,09±0,04 is derived. The result shows a deviation from theΔT=0 isotopic spin selection rule for Fermi transitions.
