一种用于远离β稳定线丰中子重核研究的实验方法

A method used to Study heavy neutron-rich nuclei far from stability

建立了一套由△Ｅβ－Ｅβ望远镜、两个高纯锗γ探测器和一个慢时钟时间－数字转换器（ＣＴＤＣ）等组成的多参数符合探测系统，利用△Ｅβ－γ符合来压低缺中子核素的γ谱线进行丰中子核素研究。研制了一台ＣＴＤＣ给出原子核衰变的时间参数，进行核半衰期研究，用γ－γ和γ－β符合来进行原子核衰变纲目研究．

A multi-parameter coincidence detector system consisting of a △Eβ-Eβ telescope, two germanium detectors and a slow clock time-to-digital converter (CTDC) has been set up. For studying neutron-rich nuclei, the △Eβ-γ coincidence is employed to reduce intensity of γ-rays from neutron-deficient nuclei. The CTDC can give nuclear decay time parameters for determining half-life of nuclear decay, showing that this detector system can be used to study nuclear decay scheme.
