We use the R-matrix approach to solve the Schrödinger equation in the optical model (OM) analysis of the elastic nucleon-nucleus scattering using a nonlocal nucleon phenomenological and microscopic optical potential (OP). The phenomenological OP is proposed by Perey and Buck while the microscopic one is proposed by T. V. Nhan Hao et al. [1]. The comparison of the obtained wave functions shows the defects of the phenomenological in the internal region. [1] T. V. Nhan Hao, B. Minh Loc, and N.
