The two-step g-cascades, following thermal neutron capture in 175Lu and terminating at 14 low-lying (Eex < 600 keV) levels or level doublets of the 176Lu nucleus, have been studied using the sum-coincidence technique using two Ge-detectors. The parameter majority of these cascades was unambiguously placed in the decay scheme. The regularity in the energies of the most intense cascades has been revealed. The results are compared with previous data for a group of deformed and spherical nuclei and with predictions of different models.
