摘要：
A family of P-stable exponentially-fitted methods for the numerical integration of the Schrodinger equation is obtained in this paper. An application to the resonance problem of the one-dimensional Schrodinger equation indicates that the new methods are generally more efficient than the previously developed exponentially-fitted methods of the same kind.
