We report the measurements on partial production cross sections of the multiple helium fragments emitted in the interactions of Si28 ions at 14.5A GeV in nuclear emulsion. Interaction mean free paths of the helium fragments have been investigated on the basis of helium multiplicity and size of the target nucleus as a function of the distance from their production points. Multiplicity scaling in the produced helium fragments is also observed.

Evidence for collective expansion in light-particle emission following Au+Au collisions at 100, 150 and 250 A·MeV

Poggi, G. ; Pasquali, G. ; Bini, M. ; et al.
Nucl.Phys.A 586 (1995) 755-776, 1995.
Inspire Record 1367235 DOI 10.17182/hepdata.36519

Light-particle emission from Au+Au collisions has been studied in the bombarding-energy range 100-250 A·MeV, using DeltaE- ER telescopes in coincidence with the FOPI detector in its phase I configuration. Center-of-mass energy spectra have been measured for Z = 1,2 isotopes emitted in central collisions at CM polar angles between 60° and 90°. Evidence for a collective expansion is reported, on the basis of the mean kinetic energies of hydrogen isotopes. Comparison is presented with statistical calculations (WIX code). For CM kinetic energy spectra, fair agreement is found between data and a recently developed transport model.

Saturation of the thermal energy deposited in Au and Th nuclei by Ar projectiles between 27 and 77 MeV/u

Jiang, D.X. ; Doubre, H. ; Galin, J. ; et al.
Nucl.Phys.A 503 (1989) 560-574, 1989.
Inspire Record 25834 DOI 10.17182/hepdata.36893

Multiplicities of neutrons and light charged particles associated with central collisions have been measured in the energy range 27–77 MeV/u for the systems 40 Ar+ 197 Au, 232 Th. The experiments demonstrate the occurrence of a saturation of the thermal energy deposited in the system around 650 MeV, corresponding to a constant internal temperature close to 5 MeV.
