Photon polarization and direction

[TeCNoYoTTa]

When a photon is produced when an atom raised to excited state return to ground state it's frequency can be calculated. but can we predict the direction and polarization of that photon.

If the atom is in a magnetic field and we know its orientation, this can be possible to some extent. But not in the way that you can say "it will fly exactly in that direction", you can just give a probability distribution.
