Abstract

Double-source interference concepts are useful in describing-within the framework of quantum theory-the response of a vibrating system, such as a diatomic molecule or an electric circuit, to a sudden change in the parameters of the vibration. The initial vibration state, depicted as an occupied quasi-elliptic band in phase space, typically intersects the corresponding elliptic band for the final vibration state in two symmetrically located diamond-shaped zones. Interference between the two contributions modulates the ‘catenary curve’ pattern of transition probabilities in their dependence on the quantum number of the final state.
