Line intensities in the conversion electron spectra of Te121 and Te123 were evaluated in a variable field, 180° focusing beta-ray spectrograph. Electron-electron coincidences were obtained between the transition pairs 82-213 kev in Te121 and 88.5-159 kev in Te123. Decay schemes for the two isomers are shown.
