Abstract

The study of nucleon-nucleus elastic scattering for spherical targets amounts to solving Schrödinger equation with a given optical potential. This potential can be obtained microscopically by taking as a starting point the interaction between two nucleons. It can also be obtained in a phenomenological way by postulating the geometry of potential and fitting parameters to reproduce experimental data. Microscopic approaches show in general terms that optical potentials are nonlocal, energy-dependent, complex and dispersive. The nonlocality of the potential leads to an integro-differential equation for the wavefunction. We present here a new version of SIDES (Schrödinger Integro-Differential Equation Solver), a code developed with the participation of Jacques Raynal, extended for nonlocal potentials with first-derivative terms.
