Fragmentation of carbon ions at 250 MeV/nucleon

Abstract

The single particle inclusive reactions $^{12}\mathrm{C}$${+}^{12}$C\ensuremath{\rightarrow}x+anything (3\ensuremath{\le}Z\ensuremath{\le}6) have been studied at 250 MeV/nucleon at nine production angles from 0\ifmmode^\circ\else\textdegree\fi{} to 4\ifmmode^\circ\else\textdegree\fi{}. Production cross sections for most isotopes (Z>2) were determined. The longitudinal and transverse momentum distributions were constructed. The results at this energy are compared to the data at other energies and to the model of Friedman. It appears that, after the Coulomb effects are separated, there is very little energy dependence in the fragmentation process.
