Semiclassical approximation of the Dirac equation in a central field
B. A. Zon, A. S. Kornev Voronezh State University, Voronezh, Russia
Abstract:
We develop a semiclassical approximation of the Dirac equation in a central field with a Coulomb asymptotic behavior. We obtain relativistic semiclassical scattering phases, energy levels of hydrogen-like ions, and a semiclassical expression for the multiplicative constant in the asymptotic expansion of the wave function of the valence electron in a relativistic multiply charged ion, which plays an important role in quantum defect theory.
Keywords:
Dirac equation, semiclassical approximation, quantum defect method.
