Exact path integral treatment of a Dirac electron for a hydrogenic atom in superstrong magnetic fields

摘要

Exact path integration is carried out for the Dirac equation of an electron in a superstrong magnetic field where the Coulomb interaction with a nucleus becomes confined along the magnetic lines of force. The energy-dependent Green function and the energy spectrum for the bound states are obtained. (author). 17 refs. (Atomindex citation 28:022248)
