Spontaneous emission and non-locality in quantum mechanics
We describe a thought experiment in which the decay rate of an ensemble of excited atoms turns out to depend on both the efficiency and geometry of the counters used to detect the emitted photons. This quantum mechanical effect, of intrinsically non-local nature, implies an enhancing of the atomic decay rate and is present under experimental conditions completely different from those giving rise to the freezing of atomic decay corresponding to quantum Zeno effect.
