We study composite particles consisting of an atom trapped on an electromagnetic vortex. The vortex core acts as a guiding center for the atom, so that the atom-vortex composite will be maintained under sufficiently gentle motions of the vortex center. We show that the adiabatic exchange of two identical atom-vortex composites generates a nontrivial geometric phase factor, and conclude that these quasiparticles should obey fractional statistics.
