Peculiarities in produced particles emission in 208Pb + Ag(Br) interactions at 158 A GeV/c

S. Vokal, A. Vokalova, A. Kravcakova +2

The angular structures of particles produced in 208Pb induced collisions with Ag(Br) nuclei in an emulsion detector at 158 A GeV/c have been investigated. Nonstatistical ring-like…
