Manuscript Title: A computer program for the calculation of angular momentum coupling
coefficients. | ||

Authors: D.F. Fang, J.F. Shriner Jr | ||

Program title: COEFF | ||

Catalogue identifier: ACGY_v1_0Distribution format: gz | ||

Journal reference: Comput. Phys. Commun. 70(1992)147 | ||

Programming language: Fortran. | ||

Computer: VAX. | ||

Operating system: VMS. | ||

RAM: 200K words | ||

Word size: 32 | ||

Keywords: General purpose, Rotation group, Angular momentum Coefficients. | ||

Classification: 4.1. | ||

Nature of problem:Values for angular momentum coupling coefficients are required for a variety of physical situations. | ||

Solution method:The program represents all numbers as arrays of prime factors, and the necessary arithmetic is performed on those arrays. | ||

Restrictions:Large values of angular momenta may cause overflows. | ||

Unusual features:The results are expressed in rational form (the quotient of two integers multiplied by the square root of the quotient of two integers). | ||

Running time:Typical time <= 1s for a single coefficient. |
