In this paper a new fourth~order explicit Runge-Kutta-Nystrom(RKN) method with dispersion of high order and FSAL technique for second-order systems of ODE with periodical solutions is introduced. The method has phase-lag order eight at a cost of three function evaluations per step or three effective...
