Abstract
Fragmentation cross-section of16O relativistic ions, at two different energies, was measured in CsI crystal. An experiment designed basically to study primary cosmic ray nuclei, was exposed to monoenergetic beam of16O ions of bevatron. Fragmentation of the ions was observed in a two layer CsI target. Each CsI crystal was 1 inch thick.
The main energy of the beam was 2.1 GeV/nucleon. A subsidiary beam of 0.5 GeV/nucleon oxygen-ions was created for this experiment alone. The number of fragmentations occurring in each crystal was used to obtain the total fragmentation cross-section at these energies. The Bradt-Peters overlap parameter was derived from these cross-sections.
