Feasibility of observing two-electron interference

Abstract

The feasibility of observing two-electron interference is considered. The detection of antibunching in an intensity cross-correlation function using coincidence-delay measurement would be the most feasible experiment. The data acquisition time to observe electron antibunching in a coherent field-emission beam is estimated by taking into account the transversal coherence with a possible experimental configuration. With the available measurement system in an optimized condition, the data acquisition time is found to be $\ensuremath{\sim}{10}^{2}$ h, being considered to be the permissible duration of measurement time.
