py3nj.wigner.drc3jj¶
- py3nj.wigner.drc3jj(two_l2, two_l3, two_m2, two_m3, ignore_invalid=False)¶
Calculate Wigner’s 3j symbol ( L1 L2 L3) (-M2-M3 M2 M3) for all the possible L1 values.
- Parameters
- two_l2: array of integers, size (…)
- two_l3: array of integers, size (…)
- two_m2: array of integers, size (…)
- two_m3: array of integers, size (…)
Since L2, …, M3 should be integers or half integers, two_l1 (which means 2 x L1) should be all integers.
- Returns
- two_l1: 1d-np.ndarray of integer, shape (n, )
The possible L1 values.
- threej: array, shape (…, n)
The value of 3J symbol
