Pair creation of spin- 1/2 particles in Minkowski spacetime is investigated\nby obtaining exact solu- tions of the Dirac equation in the presence of\nelectromagnetic fields and using them for determining the Bogoliubov\ncoefficients. The resulting particle creation number density depends on the\nstrength of the electric and magnetic fields.\n
