Slowing the Decay of an Excited Atom by the Presence of a Detector
D. R. Fredkin, Amiram Ron
Abstract
The decay of an excited is shown to slow down in the presence of a photo detector. This is similar to the behavior of an atom in a mistuned cavity, and under the conditions of the quantum Zeno effect. No external perturbing field is applied to measure the survival probability of the unstable state.
