Young's double slit experiment with excited atoms

[PaleMoon]

i would like to find the detailed calculation in the case of a two slits experiment with an excited atom.
i only found the formulas when it decays near the slits.
have you links?
thanks

i have the details for electrons with a source of photons in the middle behind the slits and detectors near them. here the interaction is near the slits.

I've no clue how precisely your set up looks like. Without a minimum description with some precision, it's impossible to answer any question in a sensible way.

i come back to this paper.
is it possible in this example to assign a density matrix to the state of this unstable atom?
thanks
