摘要：

The isotopic cross sections of residual nuclei produced in fragmentation reactions of18O projectiles impinging on a carbon target at energies near 260 MeV/nucleon were measured at the HIRFL facility in Lanzhou(China).A full identification of atomic and mass numbers of fragments was achieved from the determination of their magnetic rigidity,energy loss,and time of flight.The production cross sections for a dozen of nitrogen,carbon,and boron isotopes were determined with uncertainties below 30% for most of the cases.The obtained cross sections for N and B isotopes show a rather good agreement with previous experimental data obtained with different projectile energies.The cross sections for some C isotopes seem to exhibit a dependence on the projectile energy.A comparison of the data and several theoretical model calculations are presented.
