Branching Ratio Of The Super-Allowed Beta Decay Of C-10

In an experiment performed at the ISOLDE facility of CERN, the super-allowed ss-decay branching ratio of 10C was determined with a high-precision single-crystal germanium detector. In order to evaluate the contribution of the pile-up of two 511 keV. quanta to one of the. -ray peaks of interest at 1021.7 keV, data were not only taken with 10C, but also with a 19Ne beam. The final result for the super-allowed decay branch is 1.4638(50)%, in agreement with the average from literature.
