The canonical quantum formalism predicts that the interference pattern registered in multislit experiments should be a simple combination of patterns observed in two-slit experiments. This has been linked to the validity of Born's rule and verified in precise experiments with photons, nuclear spins, nitrogen-vacancy centers in diamond, and large molecules. Due to the expected universal validity of Born's rule, it is instructive to conduct similar tests with yet other physical systems. Here we discuss analogs of triple-slit experiment using atoms allowing tripod energy level configuration, as realizable, e.g., with alkaline-earth-metal-like atoms. We cover all the stages of the setup including various ways of implementing analogs of slit blockers. The precision of the final setup is estimated and offers improvement over the previous experiments.
