Abstract
One of the intriguing features of (Sauter-)Schwinger pair production is the Stokes phenomenon of no-pair production in some bipolar electric fields. The spin effect is studied on fermion pair production in the same electric fields of New Physics (Sae Mulli) 68, 1225 (2018), in which pair production of bosons is explained in terms of polons, simple poles with complex frequency. The Stokes phenomenon is showed to occur for specific parameters when the electric field is bipolar and changes the direction of antisymmetry in time. We compare the pair production of bosons and fermions and discuss its physical implications.
