Relativistic Oscillator Model and Delbrück scattering

Abstract
Elastic scattering of photons in a Lorentz-scalar potential via virtual spin-zero particle-antiparticle pairs (`` Delbrück scattering") is considered. An analytic expression for the Delbrück amplitude is found exactly in case of an oscillator potential. General properties of the amplitude and its asymptotics are discussed.
