用放射化学分离及γ谱学技术测量了入射能量为４７ＭｅＶ／ｕ￣（１２）Ｃ离子轰击厚靶反应产物的平均产额，获得了近１００个核素的平均生成截面。基于这些数据并借助于电荷分布及母子体关系的修正，从许多累积及部分累积产额获得了独立产额，同时得到了比靶核少３、４、５个电荷数的产物（即Ｈｇ、Ａｕ、Ｐｔ）的同位素分布曲线，由此得到了中能较轻重离子引起的深部非弹转移反应产生丰中子同位素的有效产额。
The average yield of thick target reaction products bombarded by 47 MeV / u ~ (12) C ion bombarded with incident energy was measured by radiochemical separation and γ spectroscopy, and the average cross section of nearly 100 nuclides was obtained. Based on these data and with the aid of the charge distribution and the correction of the relationship between the mother and the child, independent yields were obtained from many accumulated and partial accumulated yields and the products with 3, 4, 5 charge numbers less than the target nucleus (ie Hg, Au, Pt), the effective yield of abundance neutron isotopes generated by the deep non-bombardment reaction caused by the lighter ion in the medium can be obtained.
