Table of Clebsch–Gordan coefficients

This is a table of Clebsch–Gordan coefficients used for adding angular momentum values in quantum mechanics. The overall sign of the coefficients for each set of constant j_1, j_2, j is arbitrary to some degree and has been fixed according to the Condon-Shortley and Wigner sign convention as discussed by Baird and Biedenharn. Tables with the same sign convention may be found in the Particle Data Group's ''Review of Particle Properties'' and in online tables.
==Formulation==
The Clebsch–Gordan coefficients are the solutions to
:
|(j_1j_2)jm\rangle = \sum_^ \sum_^
|j_1m_1j_2m_2\rangle \langle j_1j_2;m_1m_2|j_1j_2;jm\rangle

Explicitly:
:
\begin
\langle j_1j_2;m_1m_2|j_1j_2;jm\rangle = \
&\delta_ \sqrt}\ \times \\
&\sqrt\ \times \\
&\sum_k \frac.
\end

The summation is extended over all integer for which the argument of every factorial is nonnegative.〔(2.41), p. 172, ''Quantum Mechanics: Foundations and Applications'', Arno Bohm, M. Loewe, New York: Springer-Verlag, 3rd ed., 1993, ISBN 0-387-95330-2.〕
For brevity, solutions with and are omitted. They may be calculated using the simple relations
:\langle j_1j_2;m_1m_2|j_1j_2;jm\rangle=(-1)^\langle j_1j_2;-m_1,-m_2|j_1j_2;j,-m\rangle .
and
:\langle j_1j_2;m_1m_2|j_1j_2;jm\rangle=(-1)^ \langle j_2j_1;m_2m_1|j_2j_1;jm\rangle .
