摘要

We present new measurements of the total and partial fragmentation cross sections in the energy range 0.3–10 ion:none; color:black" href="/science?_ob=MathURL&_method=retrieve&_udi=B6TVB-4S7BDCD-1&_mathId=mml2&_user=1067359&_cdi=5530&_rdoc=7&_acct=C000050221&_version=1&_userid=10&md5=7adebe3881f30fb7dcfb20401db69a7b" title="Click to view the MathML source" alt="Click to view the MathML source"><i>Ai> GeV of ⁵⁶Fe, ²⁸Si and ¹²C beams on polyethylene, CR39 and aluminum targets. The exposures were made at Brookhaven National Laboratory (BNL), USA, and Heavy Ion Medical Accelerator in Chiba (HIMAC), Japan. The CR39 nuclear track detectors were used to identify the incident and survived beams and their fragments. The total fragmentation cross sections for all targets are almost energy independent while they depend on the target mass. The measured partial fragmentation cross sections are also discussed.
