We show that a treatment of the radiative decay as a quantum evolution of a single physical system composed of a three-level electron subsystem and photons leads to a range of consequences depending on the electron-photon interaction and the measurement. Different treatments of the emitted photon channel the electron-photon system into a variety of final states. The theory is not restricted to the three-level system.", "revisions": [ { "version": "v1", "updated": "2005-01-19T23:59:27.000Z" } ], "analyses": { "keywords": [ "unified theory", "spontaneous emission", "consequences", "degenerate ground states", "radiative decay" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
