Photon Damping Caused by Electron-Positron Pair Production in a Strong Magnetic Field
Abstract
Damping of an electromagnetic wave in a strong magnetic field is analyzed in the kinematic region near the threshold of electron-positron pair production. Damping of the electromagnetic field is shown to be noticeably nonexponential in this region. The resulting width of the photon $γ\to e^+ e^-$ decay is considerably smaller than previously known results.
