  We present a theoretical analysis of inequivalent classes of interference
experiments with non-abelian anyons using an idealized Mach-Zender type
interferometer. Because of the non-abelian nature of the braid group action one
has to distinguish the different possibilities in which the experiment can be
repeated, which lead to different interference patterns. We show that each
setup will, after repeated measurement, lead to a situation where the
two-particle (or multi-particle) state gets locked into an eigenstate of some
well defined operator. Also the probability to end up in such an eigenstate is
calculated. Some representative examples are worked out in detail.
