本文介绍了BaF_2探测器在高分辨时间微分扰动角关联和角分布研究中的应用。可以采用核态寿命为几个ns的探针核,并能精确地测定很高的超精细相互作用频率。利用中间态半寿命为3.4ns的~(99)Tc探针核对YBaCuO,超导体的研究显示了BaF_2探测器在时间微分扰动角关联和角分布研究中的应用潜力和优点。
This paper introduces the application of BaF_2 detector in differential perturbation angle correlation and angular distribution at high resolution time. It is possible to use a probe core with a nuclear state lifetime of a few ns and to accurately measure the high frequency of hyperfine interactions. The investigation of YBaCuO using ~ (99) Tc probe with half-life in the half-life of 3.4 ns shows the potential and advantages of the BaF_2 detector in time-dependent perturbation angle correlation and angular distribution studies.
