Nonlocal potential problems in the systems with axial symmetry. — •Natasha Fominykh and Oleg Kidun — Max-Planck Institut für Mikrostrukturphysik, Weinberg 2, 06120 Halle

In this contribution we present a new approach for the calculation of the scattering and bound states of the axially symmetric systems with arbitrary nonlocal potentials. The method utilizes the formalism of the variable phase approach [1-3] and is based on the solution of the system of two integro-differential equations for the scattering amplitude and phase. We suggest a fast finite-difference scheme for the numerical implementation of our method, which requires the numerical efforts of the same order as those for the local potential case. As a particular example, we consider the separable nonlocal potential problems and the Hrtree-Fock problem.
