Abstract: Spectra of gamma rays from the ⁹⁹Mo decay have been investigated by means of HPGe-detectors. The new data on relative intensities of gamma rays were obtained for region of energy above 150 keV. The level scheme of ⁹⁹Nb was discussed. The existence of excited states 1004.06, 1072.21, 1129.14 and 1198.9 keV of ⁹⁹Nb was confirmed. The existence of 761.24 and 1171.96 keV energy levels in the decay scheme was not verified.
