| 摘 要： | 为研究中能重离子轰击天然Ｐｂ厚靶生成的较短寿命的Ｈｇ同位素产物，研制成功一套带有跑兔系统的气相热色谱装置，它可自动进行靶辐照并可实现Ｈｇ产物快速脱出、分离和收集。收集的样品被传送到低本底测量站而不破坏真空。利用此中分离半衰期２０ｓ或更短一些的核系。

| Abstract: | In order to carry out the investigations on the short life Hg isotopes produced by the intermediate energy heavy ion reactions with a natural Pb thick target,on line molten lead target gas thermochromatography separation apparatus with a rabbit system has been designed. The apparatus could operate automatically for target irradiation by using this apparatus,release and separation as well as collection of Hg product could be quick performed.The sample of collection is transferred to the low background measuring station without breaking the main vacuum.It can be easily adapted to nuclide of about 20 s or less half life.Detailed design and constructional features of the apparatus are described. |
