Abstract
Nine experimental isomeric cross-section ratios for the reactions59Co(n, γ)60Co,60Ni(n,p)60Co, and63Cu(n,α)60Co are analysed in terms of statistical theory by means of the method ofHuizenga andVandenbosch. Theγ-cascades are treated by a new model which was recently published. The results confirm the energy dependence of the spin cut-off factor for60Coσ∼U1/4 which should not be neglected. As a mean value (σ=4.3±0.3 is obtained forU=Bn=7.5 MeV in good agreement with a nuclear moment of inertia for a rigid sphere.
