Abstract
An electrostatic spectrometer was used to study the dependence of the position of theM 5 line of conversion electrons from the 2.17-keV transition in99Tc on the source thickness, in samples of different chemical compounds of Tc: metallic technetium, technetium dioxide, and pertechnate. Recommendations are given concerning the use of a source in the form of a film of metallic technetium (less than 10−7 g/cm2 thick) on a platinum substrate for calibrating electron spectrometers in the energy range of a few kiloelectron volts. A procedure is described for preparing films of metallic technetium.
