The intermolecular isotope effect in recoil tritium reactions with hydrogen and deuterium was studied by sealing off gas mixtures of He/sup 3/ with H/sub 2/ and D/sub 2/ and irradiating with a thermal neutron beam for two days, the reaction being He/sup 3/a(n.p)T. The products were then separated by gas chromatography, and their radioactivity was measured. In this way, HT/DT ratios were measured for various H/D ratios, and T is found to have a strong preference for RT formation over DT: the isotope preference is 1.55 plus or minus 0.06. With NO or O/sub 2/ added as a free radical scavenger, the preference is higher. (D.L.C.)
