Methods

__init__()
eval([label_i, spin_i, label_j, spin_j])	Evaluate the matrix element <i,s_i|l*s|j,s_j>.

__init__()

eval(label_i: str = 's', spin_i: str = 'up', label_j: str = 's', spin_j: str = 'down') → complex

Evaluate the matrix element <i,s_i|l*s|j,s_j>. :param label_i: orbital label of bra :param spin_i: spin direction of bra :param label_j: orbital label of ket :param spin_j: spin direction of ket :return: matrix element in hbar**2
