摘要：

The applicability of the method of summed amplitudes of coinciding pulses to determine radiative strength functions of heavy nuclei by measuring two-step cascade gamma-ray spectra is discussed. Experiments based on thermal neutron capture in Ba-136 and Hf-180 were carried out to test this method. The values obtained for the radiative strength functions of a wide range of primary transitions were compared with the predictions of two modifications of the giant dipole resonance model. Some insight into the characteristics of the gamma-decay of compound-states is provided by analyzing the information obtained on the two-step gamma-decay of a number of nuclei in the mass region 137 less-than-or-equal-to A less-than-or-equal-to 187.
