| 摘 要： | 用Ge(Li)探测器测量正电子在两种不同来源的铝样品中的湮没辐射,以181Hf的482keVγ,峰做为基准,重复测定湮没峰与基准峰的相对位置,精密度达到±6eV。结果表明,在两种铝样品中的电子静止质量在10eV水平上是一致的。

| Abstract: | The radiation of positron annihilation in two aluminum samples from different origins was measured with the Ge(Li) detector. Using the 482 keV γ peak of 181Hf as reference, the relative positions of the annihilation peak centers were repetitively determined, the precision of the determination reached ± 6 eV. The results show that the rest mass of electron in these two different aluminum samples is consistent on 10 eV level. |
