Robert U. Ayres,Benjamin Warrents of particle properties. Optical particle velocity, particle size and particle concentration measurements are considered and special instrumentation requirements are pointed out. It is shown that the most stringthend requirements exist for the measurements of the particle velocity. For this, las

Wolfgang Sachsrse magnetic field. It exhibits dissipationaless conduction ρ. = 0 and quantization of the Hall resistance R. = hv/e , with v-the Landau level filling number-a rational fraction. This paper will address the magneto-optics of quantum Hall states. For ideal system of coplanar electrons and holes the p
