pyarts.arts.math.dwigner3j

math.dwigner3j(M: int, J1: int, J2: int, J: int) → float

Computes the Wigner 3J symbol using floating point approximation

\[\begin{split}w_3 = \left(\begin{array}{ccc} J_1&J_2&J\\M&-M&0\end{array}\right)\end{split}\]

Note that we expect better output from the pure wigner3j() function for the same input

Parameters:

• M (int) – As above

• J1 (int) – As above

• J2 (int) – As above

• J (int) – As above

Returns:

w3 – The value

Return type:

float
