Energy dependence of the calculated yield of 176mLu isomer in reaction 175Lu(n, γ)

We calculate the yield of 176mLu isomer in dependence on neutron energy using the Huizenga-Vandenbosch and Hauser-Feshbach statistical models. The results are compared to experimental data. We discuss the impact of uncertainty in calculating the isomer yield on the isotopic ratio 176Lu/175Lu in the core of the Oklo reactor.
