3p and 3d core-level widths have been determined experimentally by the help of internal-conversion electron spectroscopy in metallic Tc99m. The Coster-Kronig broadening of an internal-conversion line has been identified in the case of the M4 transition. The existence of chemical effects on the 3d3/2 core-hole lifetime is shown for NH4TcO4. From the measured energies of the conversion peaks and from the core-level binding energies obtained earlier by x-ray photoelectron spectroscopy, the value of the E3 transition energy has been determined to be 2173.8 0.4 eV. Application possibilities of the results in resolution calibration of electron spectrometers and for x-ray width determination are briefly discussed.
