Can an antiparticle such as the antiparticle of an electron - a positron exhbit wave particle duality. We know from de Broglie, and the Davisson-Germer experiment in which we fire electrons from an electron gun, towards a double slit(carefully arranged), there is an interference pattern observed. Fire single electrons too, at a time towards the double slit and over time an interference pattern emerges.
Is this true for the antiparticles too? For instance, if we fired positrons, towards a double slit, will an interference pattern emerge- though what apparatus might capture such an antimatter interference pattern is another point of discussion(whether single positrons are fired at a time, or more). Will there be an interference pattern observed for positrons too?
