The spectrum of electrons and positrons originating from vacuum decay occurring in the collision of two noncollinear laser pulses is obtained. It displays high energy, highly collimated particle bunches traveling in a direction separate from the laser beams. This result provides an unmistakable signature of the vacuum-decay phenomenon and could suggest a new avenue for development of high energy electron and/or positron beams.
