Title of program: M2-RECURSION OF 3J-COEFFICIENTS
Catalogue Id: ACWR_v1_0
Nature of problem
Subroutine REC3JM 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.
