The state-to-state cross sections for D t Hz(u= 1, j= 1 )+HD(u'= I, j' =O-13) +H are calculated at the (very high) total energy 1.8 eV both by quasiclassical trajectories and by a well-converged quantum dynamical variational calculation on the most accurate available potential energy surface.

✦ Synopsis
The state-to-state cross sections for D+ H2( u= j= I ) -HD( u' + 1, j' = 0-13 ) +H at total energy I .8 164 eV have been calculated by accurate quantum dynamics, using larger basis sets and more stringent convergence criteria than in previous work. The cross sections differ from previous calculations by up to lo%, but they still differ from recent experiments by Kliner, Adelman and Zare by significantly more than the experimental error bars.

Integral and differential state-resolved cross sections have been calculated by the method of quasiclassical trajectories for the H t D,+HD+D reaction in the range of initial conditions of interest to recent experiments.

The reaction H+Da+HD( u'= 1, j') t D was studied using two different experimental geometries: (1) a probe-laser-induced reaction geometry and (2) an independent-photolysis laser geometry. High-energy H atoms were generated by photolysis of HI which resulted in center-of-mass collision energies of 2.
The reaction D + H2 + HD + H has been investigated in two molecular beam scattering experiments. Angular and time-of-flight distributions have been measured for the initial vibrational ground state ( u = 0) at a most probable collision energy of E,, = 1.5 eV and for the first vibrational excited sta
