摘要: 用放射化学和γ谱学技术测量47MeV/u~(12)C同~(133)Cs、~(209)Bi和~(197)Au反应近靶产物的平均截面,得到了低靶产物碘、汞、金和铂的同位素产额分布曲线,发现靶核每减少一个质子其近靶产物最可几质量与靶核之差为4～5个质量单位,靶核(~(133)Cs和~(197)Au)削裂2个质子的产物~(131)I和~(195m)Ir的截面分别为0.47±0.20和0.60±0.10mb。 The average formation cross sections of the targetlike residuals produced in theinteractions of 47MeV/u ~(12)C with ~(133)Cs、~(209)Bi and ~(197)Au targets were measured by means of theradiochemical separtion and γ-spectroscopy techniques. The mass-yield curves of I、Hg、Au、Ptisotopes were obtained. It is found that the mass difference between the target nucleus and the mostprobable products for the targetlike isotopes is about 4～5 mass units, every time the target nucleusreduces a proton...
