Interaction of quasiparticles (phonons) with a vortex produces an additional transverse force (Iordanskii force). The Iordanskii force is related to the acoustic Aharonov--Bohm effect.Connection of the effective Magnus force with the Berry phase is also discussed.20 pages, 5 figures, to be published in Proceedings of the workshop "Microscopic structure and dynamics of vortices in unconventional superconductors and superfluids", Dresden, Germany, 2000Superconductivitytext
