Low-temperature D(+) + H2 reaction: a time-dependent coupled wave-packet study in hyperspherical coordinates.

A recently proposed coupled three-dimensional time-dependent wave-packet formalism in hyperspherical coordinates is shown to yield accurate results for the reactive non-charge transfer process in the title system at collision energies as low as 100 K, where the lowest sheet of the accurate double many body expansion form for the singlet H3+ is used. The results are compared with available experimental data as well as time-independent calculations, and the agreement shown to be generally good.
