%X Abstract
A FORTRAN program is presented for the evaluation of the integral of a product of three 6-dimensional spherical harmonics over the surface of the unit 6-sphere. The functions have a classification according to the chain of groups O(6)⊃S O (2)×SU(3)⊃SO(3)⊃SO(2), introduced originally by Dragt. This scheme provides four quantum numbers plus a multiplicity label, thus giving rise to a non-orthogonal basis for which general analytic expressions are kno...
Title of program: HHMTX
Catalogue Id: ACHX_v1_0
Nature of problem
Approximate eigenvalues and eigenfunctions for a Schrodinger equation H Psi = E Psi may be obtained by diagonalization of a truncated matrix of the intrinsic Hamiltonian H with respect to a complete set of functions depending on the relative vectors. In a system of three interacting bodies the matrix elements involve integrals of a product of two and three Dragt harmonics when the relative vectors are transformed to a set of 6-dimensional spherical coordinates and the harmonics are used as basis ...
