Fragmentation cross sections of 788A MeV 28Si on carbon and polyethylene targets

• The total charge-changing cross sections do not show obvious energy dependence.
• The partial cross sections show obvious even-odd effect.
• The charge pick-up events have been observed.

The total charge-changing cross sections and the partial cross sections of silicon ions on carbon and polyethylene targets are studied at 788 A MeV by using CR-39 plastic nuclear track detectors. The results are compared with other experimental and theoretical results. The obvious even-odd effect for partial cross sections is observed.
