Abstract：
Monte Carlo Calculations of the isomeric cross section ratio for (n,2n)reaction based on the compound nuclear reaction theories and exciton-model are presented. Thecalculations are compared with experimental measurements for ⁵⁹Co (n,2n)⁵⁸Co, ⁹³Nb(n,2n)⁹²Nb and ¹⁸¹Ta(n,2n) ¹⁸⁰Ta reactions in the energy region from threshold to 20MeV. The agreemeat between calculation and experiment indicates that the present method is suitable to calculate the isomeric cross section ratio for (n,2n)reactions.
