(n, γ) Reactions in heavy nuclei: Manifestations of nuclear structure at excitation energies up to the neutron binding energy

At present, information about the excitation of 40 nuclei from the mass region 114 ≤ A ≤ 200 and about their subsequent decays into given lowly lying levels of those nuclei has been obtained for excitation energies in the region extending up to the neutron binding energy. A comparison of the experimentally observed intensities of such two-photon cascades with the results of calculations based on the statistical theory of gamma decay reveals that, in order to predict the parameters of such processes to a precision comparable to that achievable in modern experiments, it is necessary to take into account the effect of the structure of excited nuclear states up to neutron binding energy.
