The state-to-state cross sections for D + H2 (ν = 1, j = 1) → HD (ν′ = 1, j′ = 0-13) + 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. Results are compared to the recent experiment of Kliner and Zare.
