The levels up to 1.341 MeV in {sup 121}Te and up to 1.037 MeV in {sup 123}Te were excited via the {sup 121,123}Sb({ital p},{ital n},{gamma}) reaction. For the first time, lifetimes of the energy levels at 758, 807, 811, 912, 944, 1149, and 1341 keV in {sup 121}Te and 784, 895, and 1037 keV in {sup 123}Te have been measured using the Doppler shift attenuation technique. For the 831 keV level in {sup 121}Te we have given a lower limit to the lifetime.
