Isotopic cross sections of fragmentation residues produced by light projectiles on carbon near 400A MeV

Abstract

We measured 135 cross sections of residual nuclei produced in fragmentation reactions of 12C, 14N, and 13−16,20,22 O projectiles impinging on a carbon target at kinetic energies of near 400 A MeV, most of them for the first time, with the R3B/LAND setup at the GSI facility in Darmstadt (Germany). The use of this state-of-the-art experimental setup in combination with the inverse kinematics technique gave the full identification in atomic and mass numbers of fragmentation residues with a high precision. The cross sections of these residues were determined with uncertainties below 20% for most of the cases. These data are compared to other previous measurements with stable isotopes and are also used to benchmark different model calculations.
