In a stationary state
WebThe excited state is (a) never sensibly populated and (b) it is not a stationary state so has a finite lifetime. Thus the width of this state (in energy) gives the scattering some very , very small probability of occurring when the photon is non-resonant. $\endgroup$ – porphyrin. WebMay 6, 2024 · Referred to by Scottish economist Adam Smith (1723-1790), stationary state is a situation of zero growth in which the stock of goods is always the same (that is, quantity consumed equals quantity supplied in the same time period) and rewards to factors of production are at a minimum.
