  The polynomials introduced by Sister Celine cover different usual orthogonal
polynomials as special cases. Among them, the Jacobi and discrete Hahn
polynomials are of particular interest for the quantum theory of angular
momentum. In this note, we show that characters of irreducible representations
of the rotation group as well as Wigner rotation "d" matrices, can be expressed
as Sister Celine's polynomials. Since many relations were proposed for the
latter polynomials, such connections could lead to new identities for
quantities important in quantum mechanics and atomic physics.
