Abstract

The calculable R-matrix method is applied to solve the Schr\"odinger equation in the optical model (OM) analysis of the elastic nucleon-nucleus scattering using a nonlocal nucleon optical potential (OP). The phenomenological nonlocal nucleon OP proposed by Perey and Buck (PB), and the two recent versions of the PB parametrization were used in the present OM study of the elastic nucleon scattering on 27^{27}Al, 40^{40}Ca, 48^{48}Ca, 90^{90}Zr, and 208^{208}Pb targets at different energies. The comparison of the OM results given by the calculable RR-matrix method with those given by other methods confirms that the calculable RR-matrix method is an efficient tool for the OM study of the elastic nucleon-nucleus scattering using a nonlocal nucleon OP.
