The half-life of the ground state of Tc97 was found to be (2.6+/-0.4)×106 years by comparison of its K x-ray intensity with that from the 90-day Tc97m isomeric state. The LK-capture ratio of Tc97 was compared with that of Tc96; a somewhat larger ratio is indicated for the former. No γ rays were observed that could be attributed to Tc97. The relation of these results to the occurrence of technetium in certain stars and to its possible occurrence in the earth's crust is discussed. Improved measurements of the Tc98 γ-ray energies yielded values of 669+/-5 kev and 769+/-6 kev.
