摘要
介绍了Ｈｅ—ｊｅｔ带传输及Ｘ—Υ（ｔ）符合测量装置分离鉴别重缺中于远离核的原理、速度和效率；离线测试了其最佳工作条件；利用该装置在线测量了１９５，１９６Ｂｉ、１５２，１５４Ｅｒ和１５３Ｅｒ的（ＥＣ＋β＋）衰变。６条新Υ射线被确定属于１５３Ｅｒ。
A He-jet recoil tape-transport and X-Υ(t)coincidence system for separating and identifying the heavy neutyon-deficient nuclei far from the stability is described including its fundamentals, speed and efficiency.Its optimal working condition has been tested off-line.The Υ-rays from 195,196Bi and 152,153,154Er(EC+β+)decay have been measured on-line by using the system. Six new Υ-rays have been assigned to 153Er.
