Abstract : Although the research was unable to make high quality quantitative measurements on the H + D2HD + D reaction, the experience gained points important directions for state-of-the-art improvements. Turning to the H + D2 case, it is clear that at least one of the following technical advances must be made to ensure the success of such measurements: (1) a D2 purity higher than 99.5% must be obtained and if the signal-to-noise ratio is to be increased by a factor of 10, the purity of the D2 should exceed 99.995%, since the HD impurity problem was one of noise; (2) better trapping than simple condensation at a 4 K surface must be employed. The present state-ofthe-art is probably adequate to carry out detailed studies of reaction collisions between hydrogen atoms and deuterated hydrocarbons using electron impace ionization. (Author)
