Nonstatistical ring-like substructures of produced particles in azimuthal plane of a collision have been found and their parameters have been determined.8 pages, 4 figures, Report at the XVII International Baldin Seminar on High Energy Physics Problems "Relativistic Nuclear Physics & Quantum Chromodynamics", JINR, Dubna, Russia, September 27 - October 2, 2004High Energy Physics - Experimenttext
