Equations are derived for the time evolution of the reduced density operator for an (N + 1)-state atom which is damped by its coupling to a finite-temperature boson bath. General formal solutions are discussed in the limit of low temperature. Exact solutions are given for the decay of a p level in an electric field. The effects of a driving field and of transitions between the excited states on the equations are discussed. The application for the decay of elementary particles is mentioned.
