A FORTRAN 77 version of “a function subprogram in order to calculate the matrix elements of rotation operators”

Title of program: ROTATION MATRIX ELEMENTS DD Catalogue Id: AABI_v2_0 [AAFG] Nature of problem The reduced matrix elements of rotation operators are calculated. The sum is done for all the values for which the argument of the factorials are greater than or equal to zero. Each matrix element is written explicitly as a literal polynomial on the variables cos (beta/2) and sin (beta/2). Versions of this program held in the CPC repository in Mendeley Data AABI_v1_0; ROTATION MATRIX ELEMENTS D; 10.1016/0010-4655(85)90124-9 AABI_v2_0; ROTATION MATRIX ELEMENTS DD; 10.1016/0010-4655(86)90139-6 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)程序名称：旋转矩阵元DD（ROTATION MATRIX ELEMENTS DD） 目录编号：AABI_v2_0 [AAFG] 问题说明 本程序用于计算旋转算符的约化矩阵元。对所有满足阶乘参量大于等于零的取值进行求和。每个矩阵元均被显式表示为以cos(β/2)与sin(β/2)为变量的多项式。 该程序在Mendeley Data的CPC程序库中的存档版本如下： AABI_v1_0; 旋转矩阵元D（ROTATION MATRIX ELEMENTS D）; 10.1016/0010-4655(85)90124-9 AABI_v2_0; 旋转矩阵元DD（ROTATION MATRIX ELEMENTS DD）; 10.1016/0010-4655(86)90139-6 本程序源自贝尔法斯特女王大学馆藏的CPC程序库（1969-2019年）
