# A computer program for the calculation of angular-momentum coupling coefficients

## Description

Abstract A computer program COEFF is described which calculates angular-momentum coupling coefficients and expresses them as a quotient of two integers multiplied by the square root of the quotient of two integers. This is accomplished by using a representation in which an integer number is converted into an array of prime factors and by redefining the basic arithmetic functions to manipulate these arrays. The program provides the capability of calculating coupling coefficients for large angular momen...
