Feynman tells us,
"The probability that an atom will emit a photon into a particular final state is increased by the factor (n+1) if there are already n photons in that state."
4–4 Emission and absorption of photons, http://www.feynmanlectures.caltech.edu/III_04.html
The 1 in (N+1) comes from stimulated emission by the quantum vacuum?
The ground state though has the minimum energy 1/2hν?
Naively I might expect the factor (N+1) to be instead (N+1/2) because the ground state is in some sense only 1/2 the "strength" of a real quantum so its effects might be half as much?
I suspect there is a simple answer to this.
Thanks!
