摘要：
A general numerical solution of the dispersion integral relation between the real and the imaginary parts of the nuclear optical potential is presented. Fast convergence is achieved by means of the Gauss-Legendre integration method, which offers accuracy, ease of implementation and generality for dispersive optical model calculations. The use of this numerical integration method in the optical model parameter search codes allows for a fast and accurate dispersive analysis.
