The reduced rotation matrix

Title of program: DS Catalogue Id: ABOR_v1_0 Nature of problem Subprogram DS is a Fortran IV double precision function which calculates the reduced matrix elements of finite rotations in the angular momentum representation, using a standard phase convention. The four arguments of the FUNCTION are J2, twice the total angular momentum; MI2 and MF2, twice the z-projection of the total angular momentum in the inital and final coordinate systems, respectively and BETA, the Euler angle-of-rotation around y..
