DetailsDetails

  • The Wigner D-function gives the matrix element of a rotation operator parametrized by Euler angles in a -dimensional unitary representation of a rotation group when parameters , , are physical, i.e. all integers or half-integers such that .
  • For unphysical parameters, WignerD is defined by an analytic continuation.
  • Mathematica uses phase conventions where .
