Finite elements and partial waves in scattering calculations

The conventional use of pure angular momentum state representations in the algorithms for reactive scattering is discussed and the merits of alternative formulations in a finite element framework are considered with respect to possible numerical effectiveness. Four‐ and seven‐dimensional hyperspheres are discretized as means of describing three‐ and six‐dimensional scattering problems. © 1992 John Wiley & Sons, Inc.
