Phys. Rev. A 39, 398–400 (1989)Schematic model of the strength function of interacting elementary vibrationsReceived 1 August 1988; published in the issue dated January 1989 A model describing the relaxation of elementary excitations consisting of two oscillators interacting through a nonlinear coupling is discussed. Numerical solutions are shown to display motional narrowing. © 1989 The American Physical Society URL:
