Radiochemical Reaction Studies of Tritium Mixed Gases by Laser Raman Spectroscopy at TSTA

This paper reports the preliminary results of studies of the kinetics of the reactions of T2 with H2, D2, and CH4. The gas phase reactions were studied using laser Raman spectroscopy for the real-time analysis of species concentration. A novel flow cell which has low volume (ca. 4 cm3) and minimizes dead volumes is described. First order rate constants are in the range 1.4 – 2.7 days for reaction with H2 and D2, and 5 days for the reaction with CH4.
