HPGeγ探测器的γ射线能量信号与 4πΔEβ 探测器的 β射线能损信号相符合 ,再与大的BGO探测的正电子湮灭 5 11keVγ射线信号作反符合 ,由此构成的特殊探测系统在新丰中子核素2 0 9Hg的首次观察中起到了重要作用 ,显示出对从元素分离的样品中探测非常弱的丰中子同位素γ活性是一种很有效的方法
The γ-ray energy signal of the HPGeγ detector is in agreement with the β-ray energy loss signal of the 4πΔEβ detector and is inversely coincident with the large BGO-detected positron annihilation 5-11keVγ-ray signal. The special detection system formed by the HPGeγ detector in Xinfengzhong The first observation of the nuclear nuclide 2 0 9Hg played an important role, demonstrating that it is a very effective method to detect very weak abundance of abundance neutron isotope γ in samples isolated from elements
