investigate the quantum vacuum instabilities caused by the action of time-dependent electric fields; the process known as the dynamical Sauter-Schwinger pair creation. In this context, it has been demonstrated that the multislit interference and diffraction pattern in the momentum distribution of created particles is observed when a finite sequence of electric field pulses interacts with the vacuum [@Akkermans; @Li1; @Li2; @KTK; @KKproc]. Here, we generalize our recent results [@KTK; @KKproc] by comparing theoretical approaches toward particle-antiparticle pair creation based on either the spinor quantum electrodynamics (QED) or scalar QED. In other words, we are interested in investigating the effect of statistics on the Fraunhofer-type enhancements in pair production. In this context, it is important to mention the paper by Li [*et al.*]{} [@Li1] where such effects were already studied. This was done by solving the quantum Vlasov equation [@Schmidt] (see, in Appendix \[Vlasov\]). The main conclusion of [@Li1] was that, while the momentum distributions of scalar and spinor particles exhibit very similar Fraunhofer peak patterns, they are shifted relative to each other. Such shifting was ascribed to different statistics of produced particles. However, as we will show, for the parameters considered in our paper this is not necessarily the case.
