%X Abstract
Part 1 of the program generates the reduced matrix elements of the spherical tensor operator Q from which the matrix elements of all U(3) generators can be obtained. Part 2 computes the isoscalar factors for the coupling of two U(3) irreps. The basis used is symmetry adapted to SO(3)⊃SO(2) , as is desired for describing collective nuclear motion. The output of the matrix elements as well as the isosc...

Nature of problem
Elliott's nuclear SU(3) model [1,2] describes collective nuclear motion by considering the leading SU(3) irrep within the totally antisymmetric tensor product space of the valence nucleons. A rotational spectrum is expected, hence the basis for the irrep space should be symmetry adapted to the rotation group SO(3). The reduced matrix elements of the spherical tensor operator Q are needed to compute the electromagnetic transition rates. When coupling two SU(3) contained in SO(3) irreps to good SU ...
