Probing the nuclear structure of

Abstract

The nuclei 8B and 19C were investigated in breakup reactions at relativistic energies. The fragment separator FRS at GSI was used as an energy-loss spectrometer to measure the longitudinal momentum distributions of the breakup fragments after one-nucleon removal. For the case of 8B, the measured momentum distribution is in agreement with our previous experiment, but in this measurement the momentum range extends up to 175 MeV/c in the projectile frame. For 18C fragments from the breakup of 19C, we extract a much larger momentum width than the value obtained in a measurement at lower projectile energies.
