On the relation of Child and Lawton’s harmonically coupled anharmonic–oscillator model and Darling–Dennison couplinga)

Abstract

Child and Lawton’s1 model for two identifical coupled anharmonic oscillators is further discussed. It is shown that the effective Hamiltonian of that model can be transformed into a special case of the familiar Darling-Dennison resonance Hamiltonian. (AIP)
