Two-dimensional multiplicity fluctuation analysis of target residues in nuclear collisions

Multiplicity fluctuation of the target residues emitted in the interactions in a wide range of projectile energies from 500 A MeV to 60 A GeV is investigated in the framework of two-dimensional scaled factorial moment methodology.The evidence of non-statistical multiplicity fluctuation is found in 16 O-AgBr collisions at 60 A GeV,but not in 56 Fe-AgBr collisions at 500 A MeV,84 Kr-AgBr collisions at 1.7 A GeV,16 O-AgBr collisions at 3.7 A GeV and 197 Au-AgBr collisions at 10.7 A GeV.
