摘要：

The gamma-cascades following the Gamow Teller beta decay of Dy-148 0(+) have been investigated with the total absorption gamma spectrometer at GSI. Our measurements confirm that the Gamow-Teller resonant state is populated with a log ft=3.9 and that there is very little mixing of this state with the background J=1 states. In contrast to previous measurements, the experimental method presented here is sensitive to very small admixtures at high excitation energy. Previously unobserved, weak beta-branches to levels in Tb-148 are also reported.
