摘要
中子能量为14.8±0.4MeV,用直接测定产物核活性的方法,测定了^(45)Sc(n,2n)^(44)Sc反应和^(86)Sr(n,2n)^(85)Sr反应中产生的^(44m)Sc,^(44g)Sc,^(85m)Sr和^(85g)Sr的绝对截面,总截面及其比值.用Huizenga和Vandenbosch统计模型的方法进行理论计算,从而得到产物核的白旋切割因子σ.
The isomeric absolute cross-section and cross-section ratio have been measured by the direct activation method for the ^(45)Sc(n, 2n) ^(44m,g)Sc reaction and ^(86)Sr(n, 2n) ^(85m,g)Sr reaction induced by 14.8+0.4MeV neutrons. The experimental results are compared with the theoretical ones calculated by Huizenga-Vandenbosch theory and the spin cutoff parameter a is determined.
