Branching ratio of the super-allowed β decay of 10C

In an experiment performed at the ISOLDE facility of CERN, the super-allowed β -decay branching ratio of 10 C was determined with a high-precision single-crystal germanium detector. In order to evaluate the contribution of the pile-up of two 511 keV γ quanta to one of the γ -ray peaks of interest at...

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