Abstract
The stochasticity of the dissociation of the sine-Gordon breather in a n external field is studied by the method of maximum Lyapunov exponent s lambda(max). The relation between the breather dissociation rate and the asymptotic values of lambda(max) is determined. The efficiency of numerical methods for studying the dynamical chaos of physical system s is discussed.
