pyarts.arts.math.wigner6j

math.wigner6j(j1: pyarts.arts.Rational, j2: pyarts.arts.Rational, j3: pyarts.arts.Rational, l1: pyarts.arts.Rational, l2: pyarts.arts.Rational, l3: pyarts.arts.Rational) → float

Computes the Wigner 6J symbol

\[\begin{split}w_6 = \left\{\begin{array}{ccc} j_1&j_2&j_3\\l_1&l_2&l_3\end{array}\right\}\end{split}\]

Note that an appropriately large call to make_wigner_ready(fastest, largest, 6) must have been made ahead of time

Parameters:

• j1 (int) – As above

• j2 (int) – As above

• j3 (int) – As above

• l1 (int) – As above

• l2 (int) – As above

• l3 (int) – As above

Returns:

w3 – The value

Return type:

float
