Multiple fast helium fragments production from 28Si$ndash$emulsion interaction at 14.6 A GeV
Year: 2002
Type: article
Abstract: The measurements of partial production cross-sections of the multiple helium fragments emitted at 14.6 A GeV 28 Si–emulsion interactions are reported. The production rate of helium fragments due to fragmentation of 28 Si ions is studied and compared with that obtained from different projectiles at various energies. The dependence of ⟨ N α ⟩ on the mass number of the incident beams is formulated. The multiplicity distributions of the helium fragments produced in 14.6 A GeV and 3.7 A GeV 28 Si aswell as 200 A GeV 32 S exhibit KNO scaling. The characteristics of He-multiplicity events associated with and without projectile fragments of charge Z ⩾ 3 are investigated.
