Calculators written in *Java* (note: requires Java 1.1 or later)

I have written a short paper about these calculators. If you wish to cite anything concerning them, that's the thing to cite.

Here are some codes for calculating angular momentum coupling
coefficients by various authors.
Contributions in other languages are welcome.

- Fortran 90 module. Released under LGPL: Full licence here. Source and licence must be distributed together.
- C routines, contributed by Riccardo Gusmeroli

If you have any suggestions for improvement or any other comments, please email me using the address below.

There have been some other online AM coupling calculators available, but the sites come and go over time, so I've sort of stopped linking to them, except the following one. It can be much quicker than mine especially for large arguments because it is not analytic:

- At the Weizmann Institute in Israel which calculates decimal expansions for 3, 6 and 9-j symbols.
