✦ Synopsis

The reaction D+ H2( v= I ) has been investigated in a crossed molecular beam experiment at the most probable collision energy of&=0.33 eV. Angular and time-of-flight distributions have been measured and the total absolute cross section has been determined to be a&, = 0, v= 1, EC ,,,. = 0.33 eV) = 1.14 + 0.50 A2. This value, as well as the distributions, are in good agreement with the results of quasiclassical trajectory calculations ( QCT) and the reactive infinite-order sudden approximation (RIOSA) .
