摘要：

Interference effects in pair production by external fields via the Schwinger mechanism are investigated. Electric fields consisting of two time-separated pulses are shown to be capable of producing resonant behavior in the spectra of produced particles as a result of the interference between the pair-production amplitudes of the two individual pulses. No a priori assumptions about the length of the time interval between pulses relative to the individual pulse durations are made; the interference feature is seen to exist even when the interval is comparable to the pulse widths. Several numerical examples are examined.
