JavaTM 3-j Coefficient Calculator

Your browser does not support java, therefore you can't use the applet on this page. Sorry.

[*]The calculator evaluates 3-j coefficients which arise in the theory of angular momentum in quantum mechanics. The arguments should be given as half-integers, in decimal form, or as integers.
[*]As a reminder, the following conditions apply:
[*]The calculator uses java classes and methods which appear only in Java 1.1 and higher, therefore your JVM will need to support this. Recent versions of Netscape and Internet Explorer both support Java 1.1 so if you are using one of these products, and the applet doesn't appear properly, you may need to upgrade.
[*]The answer is given as an analytic expression in the first text box, and as a decimal expansion in the second in case exactness is not requisite. If the arguments are large, the analytic expression will be long and you will need to scroll the text box to see the full expression. To save time, it is not fully simplified except for small(ish) cases.
[*]If you find any problems, please email me at the address below.
