Scavenger curves for O2, Br2 and ICl scavengers have been obtained in the T + H2 system moderated by helium, argon and krypton.Results indicate that scavenger competition is significant with all three scavengers but that the behaviour of oxygen scavenger

During the course of an investigation on chemical behaviors of hydrogen isotopes in quantum media, non-statistical formation of ortho-T2 was observed in recombination reaction of T+T+3,4He→T2+3,4He in liquid su

Recoil T atom reactions were studied in Xe-H2-D2 mixtures at 77 K. The isotope effect on the T-atom reaction with H2 and D2 (k(T+H2{HT+H)/k(T+D2{DT+D)) was measured on the basis of the HT and DT yields. The isotope effect (k(T+H2)/k(T+D2)) is 1.1 in the range of hydrogen concentrations of 0.1 - 1.0 mol%. Since the small isotope effect (1.1) is similar to the isotope effect (1.0) for a hot T-atom reaction in the gas phase, recoil T atoms are not thermalized at these concentrations in solid xenon and form HT and DT by means of hot-atom reactions. At concentrations of hydrogen of less than 0.1 mol%, the recoil T atoms are thermalized before they encounter the solute hydrogen. The isotope effect increases with a decrease in the hydrogen concentration and amounts to 3.1 at a hydrogen concentration of 0.01 mol%. Since a large isotope effect is expected for the tunneling reaction of T atoms, the large isotope effect (3.1) at 0.01 mol% hydrogen was interpreted in terms of the tunneling reaction of thermalized T atoms. The present results in the solid xenon-hydrogen mixtures were compared with those in the gaseous xenon-hydrogen mixtures reported previously. It was concluded that hot T atoms in the solid xenon at 77 K are deactivated much less effectively than in the gas phase and that they migrate long distances with excess kinetic energies.

In the reaction of recoil tritium, produced by the He3(n,p)T reaction, with para-H2-enriched mixtures of H2 with D2 the HT/DT ratio obtained from unmoderated systems (i.e. reaction observed in the high energy 'hot' region) is almost independent
