Photon-Axion conversions in transversely inhomogeneous magnetic fields
arXiv:1003.0410
Abstract
We compute the photon-axion conversion probability in an external magnetic field with a strong transverse gradient in the eikonal approximation for plane waves. We find it typically smaller than a comparable uniform case. Some insights into the phenomenon of photon-axion splitting are given.
