An analytical result for Euler-Heisenberg effective action, valid for electron spin g ? factor | g | < 2 , was extended to the domain | g | > 2 via discovered periodicity of the effective action. This allows for a simplified computation of vacuum instability modified by the electron’s measured g = 2.002319 . We find a strong suppression of vacuum decay into electron positron pairs when magnetic fields are dominant. The result is reminiscent of mass catalysis by magnetic fields.
