摘要We report a theoretical study of the escape rates of the Henon-Heiles system above threshold. An analytic formula for the escape rate as a function of energy is presented. We also simulated the escaping process by following the motions of a large number of particles. Two algorithms are employed to solve the equations of motion. One is the Runge-Kutta-Fehlberg method, and another is a recently proposed fourth order symplectic method. Our simulations show the escape of Henon-Heiles system follows exponential laws. We extracted the escape rates from the time dependence of particle numbers in the Henon-Heiles potential. The extracted escape rates agree with the analytic result. Close to threshold we find the rate alpha(Delta E) can be written as a series expansion, the first term of this expansion is 4/3 Delta E.
