Pecularities in produced-particle emission in {sup 208}Pb+ Ag(Br) interactions at 158 A GeV/c

The angular structures of particles produced in {sup 208}Pb-induced collisions with Ag(Br) nuclei in an emulsion detector at 158 A GeV/c have been investigated. Nonstatistical ringlike substructures in the azimuthal plane of the collision have been found and their parameters have been determined. An...

description The angular structures of particles produced in {sup 208}Pb-induced collisions with Ag(Br) nuclei in an emulsion detector at 158 A GeV/c have been investigated. Nonstatistical ringlike substructures in the azimuthal plane of the collision have been found and their parameters have been determined. An indication of the formation of ringlike substructures from two symmetrical emission cones, one in the forward and the other in the backward direction in the center-of-mass system, has been obtained. The ringlike substructures' parameters have been determined. The experimental results are in an agreement with I.M. Dremin's idea that the mechanism of the ringlike substructures' formation in nuclear collisions is similar to that of Cherenkov electromagnetic radiation.
