An independent measurement of the 12C(, )16O cross section with the Karlsruhe 4 BaF2 detector

Many measurements of the 12C(, )16O cross section have been performed up to now but only a few could measure at energies as low as 1 MeV. All of these measurements at low energy have been carried out using Germanium detectors. The low gamma-ray efficiency of these detectors was compensated by very i...

Description
Summary:Many measurements of the 12C(, )16O cross section have been performed up to now but only a few could measure at energies as low as 1 MeV. All of these measurements at low energy have been carried out using Germanium detectors. The low gamma-ray efficiency of these detectors was compensated by very intense beam currents, which may cause considerable uncertainties due to severe target degradation. A verification of these data with a completely different approach, which could reveal systematic uncertainties, was still missing.The realization of such an independent measurement was performed with the Karlsruhe 4 BaF2 array. Due to its high gamma-ray efficiency the beam current could be substantially reduced thus minimizing the thermal load of the target and avoiding sputtering effects.
