Three-dimensional quantum mechanical reactive scattering using symmetrized hyperspherical coordinates

We report here the first three-dimensional (3D) reactive scattering calculations using symmetrized hyper-spherical coordinates (SHC). They show that the 3D local hyper-spherical surface function basis set leads to a very efficient computational scheme which should permit accurate reactive scattering calculations to be performed for a significantly large number of systems than has heretofore been possible.
