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.

程序标题：3J 系数递归计算
问题性质
子程序 REC3JJ 通过递归方程的精确解来生成 3j 系数。该算法相较于基于显式表达式的算法，在效率与精度方面均有显著提升，尤其在需要完整 3j 系数集合的常见情形中尤为突出。该算法对于分子动力学问题中出现的较大量子数具有数值稳定性。
