Programs for the coupling of spherical harmonics

Title of program: YLM-COUPLING Catalogue Id: AARL_v1_0 Nature of problem The subroutines GAUNT and RECYLM allow the linearization of the product of two spherical harmonics. The summation limits are determined by certain selection rules for the GAUNT coefficients. Versions of this program held in the CPC repository in Mendeley Data AARL_v1_0; YLM-COUPLING; 10.1016/0010-4655(82)90031-5 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)程序标题：YLM-COUPLING 目录编号：AARL_v1_0 问题性质：子程序GAUNT和RECYLM能够实现两个球谐函数乘积的线性化。求和极限由GAUNT系数的特定选择规则确定。 CPC资源库中Mendeley数据存储的该程序版本 AARL_v1_0；YLM-COUPLING；10.1016/0010-4655(82)90031-5 本程序已从贝尔法斯特女王大学（1969-2018年）所持有的CPC程序库中导入。
