We have analyzed the pseudorapidity spectra of charged relativistic particles with β > 0.7 produced in Pb + Em (at energy 158 A GeV) reactions as a function of centrality. The relativistic nucleus beams were obtained from SPS machine. The number of g-particles (particles with 0.23 ≤ β ≤ 0.7) has been used to fix the centrality. We have applied the maximum entropy method to analyses the spectra and found some selected pseudorapidity values—nontrivial structure.
