We study the production of massive fermions in arbitrary vector andaxial-vector classical backgrounds using effective action techniques. Aperturbative calculation shows the different features of each field and inparticular it is seen that pure temporal axial fields can produce particleswhereas it is not possible for a pure vector background. We also analyze from anon-perturbative point of view a particular configuration with constantelectric and axial fields and show that the presence of the axial backgroundinhibits the production from the electric field.Comment: 10 pages, 1 figure, RevTeX; minor corrections, version to appear in Phys. Rev.
