Title: An independent measurement of the 12C({alpha}, {gamma})16O cross section with the Karlsruhe 4{pi} BaF2 detector

Abstract

Many measurements of the 12C({alpha}, {gamma})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{pi} 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.

  • Neutron capture cross section measurements on many of the actinides are complicated by low-energy neutron-induced fission, which competes with neutron capture to varying degrees depending on the nuclide of interest. Measurements of neutron capture on 235U using the Detector for Advanced Neutron Capture Experiments (DANCE) have shown that we can partially resolve capture from fission events based on total photon calorimetry (i.e. total {gamma}-ray energy and {gamma}-ray multiplicity per event). The addition of a fission-tagging detector to the DANCE array will greatly improve our ability to separate these two competing processes so that improved neutron capture and (n,{gamma})/(n,fission) cross sectionmore » ratio measurements can be obtained. The addition of a fission-tagging detector to the DANCE array will also provide a means to study several important issues associated with neutron-induced fission, including (n,fission) cross sections as a function of incident neutron energy, and total energy and multiplicity of prompt fission photons. We have focused on two detector designs with complementary capabilities, a parallel-plate avalanche counter and an array of solar cells.« less
  • The {sup 237}Np(n,{gamma}){sup 238}Np cross section has been measured in the neutron energy range from 20 meV to 500 keV using the DANCE array at the Los Alamos National Laboratory. This new facility allows experiments with submilligram samples and is therefore well suited to investigate isotopes with half-lives as low as a few hundred days. In this benchmark measurement, only 0.42 mg of {sup 237}Np was sufficient to determine differential cross sections relative to the well-known resonance at 0.5 eV. The thermal cross section was measured to {sigma}{sub 2200m/s}=177{+-}5 barn, {sigma}{sub kT=25.3meV}=167{+-}4 barn and the resonance integral to RI=693{+-}6 barn.
  • Preparation for direct measurement of 12C+4He{yields}16O+{gamma} reaction at stellar energy has been made in Kyushu University tandem laboratory (KUTL) since 1914. We plan to measure the reaction at Ecm = 2.4-0.7 MeV where the cross section is estimated to be 60 nbarn-1pbarn. Many instrumental developments have been made for a 12C beam, a windowless helium gas target, 16O detection, background reduction. We started the measurement in 2006.
  • The Detector for Advanced Neutron Capture Experiments (DANCE) is a 162-element 4{pi} BaF2 array designed to make neutron capture cross-section measurements on rare or radioactive targets with masses as little as one milligram. Accurate capture cross sections are needed in many research areas, including stellar nucleosynthesis, advanced nuclear fuel cycles, waste transmutation, and other applied programs. These cross sections are difficult to calculate accurately and must be measured. The design and initial performance results of DANCE is discussed.
  • Experimental values are reported for the differential cross sections for elastic photoproduction of ..pi../sup 0/ mesons from helium nuclei at photon energies 1.5--4.5 GeV in the angle region theta/sub ..pi../ = 2--8/sup 0/. The parameters of the ..omega..-meson trajectory are obtained. The work was carried out in the bremsstrahlung beam of the Erevan synchrotron.
