Abstract
The β-spectrum of the second non-unique forbidden 9/2+−5/2+ transition in the decay of99Tc has been investigated with a 4π – Si (Li)-semiconductor-spectrometer. The shape factor has been determined: S(W)=k (1−3.97 W+1.15/W+3.05 W2).
It was also possible to fit the data with the normal ξ-Approximation to the theoretical shape factorS(W)=k(q12+0.54 p2).
The second forbidden 2+− 0+ β−-transition in the decay of36Cl was reinvestigated to test the spectrometer as well as the fitting-technique.
