Parameters:

isympy_quant

The nuclear spin quantum number I.

j_lsympy_quant

The electronic total angular momentum quantum number J of the lower state.

f_lsympy_quant

Returns:

outsympy_core | float

The q component of the spherical dipole matrix elements A_q(F_l, m_l, F_u, m_u) between two hyperfine Zeeman states of an electric transition with quantum numbers j_l and j_u. See [Brown et al., Phys. Rev. A 87, 032504 (2013)].
