Abstract：
A new value for the emission probability of 137.144 keV γ-rays from ^186gRe decay is recommended to be (9.47± 0.03)/%. Using this value the measured cross sections for ¹⁸⁷Re(n,2n)^186mRe and ¹⁸⁷Re(n,2n)^186gRe reactions around 14 MeV are analyzed, and the cross section for ¹⁸⁷Re(n,2n)^{186m + g}Re reaction at 14.8 MeV is (2213± 116) mb. The UNF code was adopted to calculate the cross sections for the ¹⁸⁷Re(n,2n)^{186m + g}Re reaction below 20 MeV, fitting to the value (2213± 116) mb at 14.8 MeV using a set of optimum neutron optical potential parameters which were obtained based on the relevant experimental data of rhenium. The isomeric cross section ratio for the ¹⁸⁷Re(n,2n)^186m,gRe reaction was analyzed using the V-H method based on nuclear statistical theory. Combining these calculated results, the excitation functions for the ¹⁸⁷Re(n,2n)^186mRe and ¹⁸⁷Re(n,2n)^186gRe reactions were obtained. The obtained results are in good agreement with the available experimental data.
