| Nov 13, 2015 at 14:23 | comment | added | user929304 | Thanks for your answer. So in either scenario, magnetic field on or off, the symmetry is preserved? (in the off case, it is trivial as you explained, but in the on case, the overall system before emission is no longer in a superposition of all possible states, due to the presence of the external field, or as you say, before and after emission, we have axial symmetry.) where am I going wrong in this? | |
