Abstract

We investigated the bound-state spectrum of a particle with spin F>~12 in the magnetic field of a thin current-carrying wire. We prove the existence of infinitely many bound states for any F. The bound-state energies closely follow a Coulomb-like behavior with an effective angular momentum *, suggesting a high adiabaticity of the system. Numerical results (F=12, , 3) are well approximated by a single simple formula for the quantum defect, which is more accurate than the approximations given in the literature. We find a qualitative disagreement with the result obtained by adiabatic approximation.
