In an experiment performed at the ISOLDE facility of CERN, the super-allowed \(\beta \)-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 \(\gamma \) quanta to one of the \(\gamma \)-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.

在CERN的ISOLDE设施中进行的实验中，使用高精度单晶锗探测器确定了\（^ {10} \） C的超允许\（\ beta \）-衰变分支比。为了评估两个511 keV \（\ gamma \）量子的堆积对1021.7 keV处感兴趣的\（\ gamma \）-射线峰之一的贡献，数据不仅采用\（^ {10} \） C，但也使用\（^ {19} \） Ne光束。超允许衰减分支的最终结果为1.4638（50）％，与文献中的平均值一致。
