We obtain exact solutions of the Dirac equation in $2{+}1$ dimensions and
the electron energy spectrum in the superposition of the Aharonov–Bohm
and Coulomb potentials, which are used to study the Aharonov–Bohm effect for
states with continuous and discrete energy spectra. We represent the total
scattering amplitude as the sum of amplitudes of scattering by
the Aharonov–Bohm and Coulomb potentials. We show that the gauge-invariant phase
of the wave function or the energy of the electron bound state can be
observed. We obtain a formula for the scattering cross section of
spin-polarized electrons scattered by the Aharonov–Bohm potential. We
discuss the problem of the appearance of a bound state if the interaction
between the electron spin and the magnetic field is taken into account in
the form of the two-dimensional Dirac delta function.
Keywords:
Aharonov–Bohm effect, scattering amplitude, polarized electron, bound state.
