论文摘要
在CERN的Isolde设施进行的实验中，用高精度的单晶晶锗探测器确定了10C的超允许的β-末期分支比率为10C。为了评估两个511 keVγ量子堆积对1021.7 keV感兴趣的伽马射线峰之一的贡献，数据不仅使用10c，而且还以19ne梁获取。与文献的平均值一致，超允许衰减分支的最终结果是1.4638（50）％。
In an experiment performed at the ISOLDE facility of CERN, the super-allowed beta-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 gamma quanta to one of the gamma-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.
