| Outline of Final Research Achievements |
We have studied the Aharonov--Bohm quantum effect in resonances through a simple scattering system in two dimensions. The scattering system consists of four scatterers, two obstacles and two scalar potentials with compact supports, where the obstacles are placed between two supports and shield completely the support of magnetic fields. The field does not influence particles from a classical mechanical point of view, but quantum particles are influenced by the corresponding vector potential which does not necessarily vanish outside the obstacles. We have shown that the resonances are generated near the real axis by the trapping phenomenon between the scatterers and that the location depends on the location of the obstacles as well as on the magnetic fluxes.
