PROGRAM LIBRARY JINRLIB Clebsch2  calculation of simple kind for ClebschGordan coefficient. 

Language: Fortran Real*8 function Clebsch2(k,n) calculates coefficient Function is free upon typical overflow errors while direct calculation of factorials. Being a descendant of MPI_AllReduce operation, function is a typical collective job for known MPIpackage. It may be effectively used in parallel MPI applications. Sources and detailed description of Clebsch2 are submitted.
