Mean density of level crossings whose duration exceeds a certain value for a low-friction nonlinear oscillator.
A system that exhibits nonlinear oscillations in the presence of low friction and weak fluctuations is considered. An expression for the mean density of level crossings whose duration exceeds a certain value is derived under the assumption of the high Q factor of the oscillations.
