Accurate quantum calculations on three-body collisions in recombination and collision-induced dissociation. I. Converged probabilities for the H+Ne2 system

The exact quantum theory of atomic recombination and collision-induced dissociation (CID) is presented using hyperspherical coordinates. Delves’ coordinates are emphasized, methods for doing numerically exact calculations are discussed and implemented, and fully converged dissociation probabilities (J=0) are presented for a model H+Ne2⇌H+Ne+Ne system. These are the first accurate CID calculations reported for any atomic system in the full three-dimensional physical space.
