A temporally quantized theory of emission and absorption of radiation

The temporally quantized theory constructed recently to account for presumed strictly-irreversible evolution of dynamically isolated and localized nonrelativistic quantum system is used to describe the processes of emission, absorption and fluorescence of radiation when such systems interact with otherwise isolated quantized radiation-fields. A Quasi-Two-State N-Level Radiative Model of systems, introduced in order to do so in precise nonperturbative terms, reveals the existence of Spectroscopically Equivalent Transitions. For these, initial transition-probability-rates and initial decay-rates derived for the processes depend identically on the frequency of the radiation involved. They differ from that derived for the initial damping-rates of their ensuing oscillatory behavior. The temporally asymptotic transition-probabilities derived for them differ even more. For intermediate lapses of time, the modulation frequencies of the radiation emitted and/or absorbed and the decay-rate constants associated with their damping satisfy a universal inverse-proportionality between them. The possible use of these expressions to test the theory is described.
