Phys. VL - 28 IS - 4 SE - Papers DO - 10.15625/0868-3166/28/4/12760 UR - https://vjs.ac.vn/index.php/cip/article/view/12760 SP - 323 AB - The calculable R-matrix method is applied to solve the Schr ̀ˆodinger equation<br />in the optical model (OM) analysis of the elastic nucleon-nucleus scatter-<br />ing using a nonlocal nucleon optical potential (OP). The phenomenological<br />nonlocal nucleon OP proposed by Perey and Buck (PB), and the two recent<br />versions of the PB parametrization were used in the present OM study of the<br />elastic nucleon scattering on 208 Pb and 27 Al targets at different energies. The<br />comparison of the OM results given by the calculable R-matrix method with<br />those given by other methods confirms that the calculable R-matrix method<br />is an efficient tool for the OM study of the elastic nucleon-nucleus scattering<br />using a nonlocal nucleon OP.
