Effect of magnetic fields on bound localized electron states

An approximate analytic solution for the ground electron state are found to the Schroedinger equation for a combination of a uniform magnetic field and single attractive delta-potential. Effect of the magnetic field on this bound localized electron state is discussed. We show that above effect leads to appearing the probability current density in some region centered in the point of the delta-potential as well as to enlarging (for a number of physical models) the localization region of the electron in the plane perpendicular to the magnetic field. We are expected that these properties can be of importance for real quantum mechanical systems.
