Title of program: J1-RECURSION OF 3J-COEFFICIENTS Catalogue Id: ACWQ_v1_0 Nature of problem Subroutine REC3JJ generates 3j-coefficients from the exact solution of a recursion equation. The algorithm is more efficient and accurate than those based on explicit expressions, particularly, in the commonly arising case in which a complete set of 3j-coefficients is needed. The algorithm is numerically stable for large quantum numbers which occur in problems of molecular dynamics.
