Abstract
The influence of a small difference between the frequencies of the nor mal modes of a two-dimensional nonlinear oscillator on the onset of st ochasticity is studied. The energy half-width of the stochastic layer in the vicinity of the separatrix is calculated using Chirikov's appro ximation. The nonmonotonic dependence of the half-width on the deviati on from resonance and the eventual vanishing of the stochastic layer a re found.
