Two-step cascades from the ¹⁹² Os(n_th,g)¹⁹³Os reaction were studied in a g- g coincidence measurement with two HPGe detectors. The decay scheme of ¹⁹³Os was established up to the excitation energy of about 3 MeV. The excitation spectrum of intermediate levels of most intense cascades was found to be practically harmonic.
