[en] A short survey is given about the work performed by the Nuclear Spectroscopy Research Group of the Institute in the last few years. The nuclei under investigation (^9798100Tc and ⁹⁴⁹⁶Nb) were produced via (p,n) reactions from enriched targets. The γ-, γγ-coincidence, and conversion electron spectra of the reactions were taken with Ge(Li), 'thin-window' hyperpure Ge, and superconducting magnet transporter Si(Li) spectrometers. The energies and the intensities of the observed radiations as well as the excitation functions of the reactions were measured. Level schemes; multipolarities of transitions; energies, spins and parities of nuclear levels have been deduced. The level schemes have been compared with the results of recent shell model calculations. (Auth.)
