Analytic angular momentum coupling coefficient calculators ☆

Abstract We describe a Java implementation of a suite of programs to calculate analytically Clebsch–Gordan coefficients, and 3j, 6j and 9j symbols used in the quantum theory of angular momentum. Title of program: Cleblet Catalogue Id: ADQG_v1_0 Nature of problem Problems involving the quantum mechanical theory of angular momentum often involve the use of angular momentum coupling coefficients, which the presented code evaluates. Versions of this program held in the CPC repository in Mendeley Data ADQG_v1_0; Cleblet; 10.1016/S0010-4655(02)00462-9 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)摘要 本文介绍了一套Java程序实现，用于解析计算角动量量子理论中所使用的Clebsch–Gordan系数（Clebsch–Gordan coefficients）以及3j、6j和9j符号。 程序名称：Cleblet 目录编号：ADQG_v1_0 问题性质 涉及量子力学角动量理论的问题通常需要使用角动量耦合系数，本程序即可对其进行求值计算。 Mendeley数据平台CPC程序库中收录的本程序版本： ADQG_v1_0；Cleblet；10.1016/S0010-4655(02)00462-9 本程序源自贝尔法斯特女王大学所维护的CPC程序库（1969-2019年）
