wigner6j

pyarts.arts.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

$$\begin{array}{r}{w}_6=\left\{\begin{array}{ccc}{j}_1& j_2& j_3\\ l_1& l_2& l_3\end{array}\right\}\end{array}$$

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
