摘要
根据蒸发模型和激子模型,在一定的假设和近似下建立了(n,2n),(n,3n),(n,x)(x=p,a,d,t, ̄3He),(n,np+pn),(n,na+an).及(n,γ)等十个反应道的中子核反应截面的参数化理论公式。公式中仅含最灵敏的参数,根据所建立的参数化理论公式,编制了参数化理论公式拟合分析程序SFF。与实验数据的比较表明:参数化的理论公式可以很好地描述实验数据。
Based on the evaporation model and exciton model, under some assumptions andapproximations, parameterized model theory forniulas of excitation functions for ten reactions, in-cluding ( n,2n ) , ( n, 3n ) , ( n, x ) , ( x = p, a, d, t ,  ̄3He ) , ( n, np + pn), ( n, na + an ) and ( n, γ) , areestablished. Only the most sensitive parameters are included in the formulas. According to theseformulas, a code SFF to analyse the measured data are developed. The comparison of the resultswith the experimenlal data demonstrates that the parameterized formulae can describe the experi-mental data very well .
