Electric dipole transition between hyperfine levels of the ground state

  1. Aug 10, 2009 #1
    microwave can be used to engineering potentials for alkali atoms

    i find that in the literature, people only take the magnetic dipole transition into account

    why the electric dipole transition is neglected?

    is it forbidden?

    The hyperfine levels are coupled by magnetic transitions, not electric ones.
