[en] The nucleus ⁹⁹Tc has been studied in Coulomb excitation with ⁴He and ¹⁶O, and 13/2⁺ and 11/2⁺ states are suggested at 762.0 and 726.7 keV, respectively. Two new levels at 625.4 and 1081.4 keV were established on basis of γ-γ coincidence relations. The lifetimes of the levels at 726.7, 761.7, 762.0 and 1081.4 keV were measured by means of the Doppler shift attenuation method using ¹⁶O ions and the half-lives obtained were 1.8+-0.2, 0.7+-0.4, 2.4+-0.3 and 0.9+-0.3 ps, respectively. With exception for the lowest 5/2⁺ state the level energies and reduced E2 and M1 transition probabilities are in fair agreement with the values calculated within the cluster-phonon coupling (Alaga) model.
