Under 5-Mev proton and 10-Mev deuteron bombardments on natural Mo and on electro-magnetically enriched Mo isotopes, activities of 2.7-hour, 47-minute, and 4.5-minute half-lives are found to be produced from Mo92. The relative cross sections for the production of these activities are 25:127:1, respectively. On comparing these figures with those for the (p,n):(p,γ ) reactions from Mo95, the 47-minute activity is assigned to Tc92, and the 2.7-hour and the 4.5-minute activities to Tc93. Tc92 decays by K-capture only attended with 1.5-Mev γ-rays. For the 2.7-hour Tc93, the decay is 93 percent by K-capture and 7 percent by emission of positrons of maximum energy 0.83 Mev. There are also γ-rays of energy 2.0 Mev associated with this activity.
