Characteristic study of proton and helium projectile fragments

A projectile (⁸⁴Kr₃₆) having kinetic energy around 1A GeV has been used to expose NIKFI BR-2 emulsion target at GSI, Darmstadt, Germany. A total of 700 inelastic events has been identified and used in the present studies on projectile fragments. The multiplicity and normalized multiplicity of projectile's fragment are correlated with the compound particles, shower particles, black particles, grey particles. It is found that projectile's fragment is strongly correlated with compound particles and shower particles rather than other particles. The average multiplicity of projectile's fragment increases with increasing compound, shower and heavily ionizing charge particles. The multiplicity distribution of the projectile's fragment emitted in the ⁸⁴Kr₃₆ - emulsion interaction at around 1GeV per nucleon with different target has been well explained by KNO scaling. In this report, we will present the results of our investigations on the projectile's fragment multiplicity and probability distributions with ⁸⁴Kr₃₆ emulsion collision at around 1 GeV per nucleon.
