描述了用于兰州在线同位素分离的FEBIAD靶 -离子源的改进、最新进展和结果。经过改进后
在线同位素分离器对Xe的分辨本领由原来的 360提高到 60 0
对199Hg的在线测量效率提高了一个数量级
并测出了Hg、At、Rn等元素的一系列放射性同位素产物及生成截面为 5×10 - 34 m2 的2 0 8Hg衰变的能量最高的一条γ线。
The modification
new progress and experimental results of the FEBIAD ion source used for isotope separation on-line in Lanzhou were described. After modification
the resolving power of ISOL is increased from 360 to 600 for Xe and efficiency for 199 Hg is higher by an order of magnitude than before. The modified FEBIAD target-ion source has been successfully applied to separate isotopes of Hg
At and Rn. The γ-ray with highest energy of 1.234MeV from the decay of 208 Hg which has a production cross section of 5×10 -34 m 2 can be measured.
