Can an antiparticle such as the antiparticle of an electron - a positron exhibit 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?

Antiparticles have the same duality, but you have to take their annihilation with your equipment's ordinary matter into account before you do your experiment.

The wave particle duality applues to EVERYTHING. Larger particles have higher frequencies and so scatter more/behave more like a particle.. with the same mass a positron will behave the same way as an electron.
