    "abstract": "We study the spontaneous de-excitation and excitation of accelerated atoms on\narbitrary stationary trajectories (``generalized Unruh effect\u0027\u0027). We consider\nthe effects of vacuum fluctuations and radiation reaction separately. We show\nthat radiation reaction is generally not altered by stationary acceleration,\nwhereas the contribution of vacuum fluctuations differs for all stationary\naccelerated trajectories from its inertial value. Spontaneous excitation from\nthe ground state occurs for all { accelerated stationary} trajectories and is\ntherefore the ``normal case\u0027\u0027. We furthermore show that the radiative energy\nshift (``Lamb shift\u0027\u0027) of a two-level atom is modified by acceleration for all\nstationary trajectories. Again only vacuum fluctuations give rise to the shift.\nOur results are illustrated for the special case of an atom in circular motion,\nwhich may be experimentally relevant.",
