摘要：
The investigation of the impact of the vanishing of the phase-lag and its first and second derivatives on the efficiency of a four-step Runge-Kutta type method of sixth algebraic order is presented in this paper. Based on the above mentioned investigation, a Runge-Kutta type of two level four-step method of sixth algebraic order is produced. The error and the stability of the new obtained method are also studied in the present paper. The obtained new method is applied to the resonance problem of the Schrodinger equation the efficiency of the method to be examined.
