研究了从放射性产物或其递次衰变子体的γ放射性测量来提取第一代产物独立截面的技术。它适用于在束快化学元素分离样品中同位素独立截面的确定。运用这套技术进行了６００ＭｅＶ１８Ｏ轰击厚天然铅靶后分离出来的汞同位素分布的测量，共得到从１８０Ｈｇ至２０９Ｈｇ２０余种同位素的独立截面
The technique of extracting independent cross-sections of first-generation products from gamma-radioactivity measurements of radioactive products or their progeny-decaying progenitors was studied. It is suitable for the determination of isotope independent cross-sections in beam-fast chemical elemental separation samples. The mercury isotope distribution measured after the 600 MeV 18 O bombardment of a thick natural lead target was measured using this technique. A total of 20 independent isotopes ranging from 180 to 209 Hg
