Abstract

Abstract: We measured the Coulomb dissociation of 16 O into 4 He and 12 C at the R 3 B setup in a first campaign within FAIR Phase 0 at GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt. The goal was to improve the accuracy of the experimental data for the 12 C( α, γ ) 16 O fusion reaction and to reach lower center-ofmass energies than measured so far. The experiment required beam intensities of 10 9 16 O ions per second at an energy of 500 MeV/nucleon. The rare case of Coulomb breakup into 12 C and 4 He posed another challenge: The magnetic rigidities of the particles are so close because of the same mass-to-charge-number ratio A/Z = 2 for 16 O, 12 C and 4 He. Hence, radical changes of the R 3 B setup were necessary. All detectors had slits to allow the passage of the unreacted 16 O ions, while 4 He and 12 C would hit the detectors' active areas depending on the scattering angle and their relative energies. We developed and built detectors based on organic scintillators to track and identify the reaction products with sufficient precision.
