  We investigate the possibility of observing a magneto-transverse scattering
of photons from alkaline-earth-like atoms as well as alkali-like ions and
provide orders of magnitude. The transverse magneto-scattering is physically
induced by the interference between two possible quantum transitions of an
outer electron in a S-state, one dispersive electric-dipole transition to a
P-orbital state and a second resonant electric-quadrupole transition to a
P-orbital state. In contrast with previous mechanisms proposed for such an
atomic photonic Hall effect, no real photons are scattered by the
electric-dipole allowed transition, which increases the ratio of Hall current
to background photons significantly. The main experimental challenge is to
overcome the small detection threshold, with only 10^{-5} photons scattered per
atom per second.
