VOID ANALYSIS OF TARGET RESIDUES AT SPS ENERGY

This paper presents new data on void analysis of target residues in ultrarelativistic nucleus–nucleus interaction. The study reveals a set of interesting observations. Void probability shows a scaling behavior at high energy (32 S –AgBr interactions at 200 A GeV) in both forward and backward hemisphere. Whereas such behavior is absent at low energy (16 O –AgBr interactions at 60 A GeV) in backward hemisphere.
