Analytical expressions for the dispersive contributions to the nucleon-nucleus optical potential. Physical Review C - Nuclear Physics, 67 (6), 067601-1-067601-3.0556-2813 (impreso)1089-490X (electrónico)http://hdl.handle.net/11441/62381Analytical solutions of dispersion relations in the nucleon-nucleus optical model have been found for both volume and surface potentials. For the energy dependence a standard Brown-Rho function has been assumed for both the volume and surface imaginary contributions multiplied in this later case by a decreasing exponential function. The solutions are valid for any even value of the powers appearing in these functional forms.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1103/PhysRevC.67.067601
