Neutron capture and total cross-section measurements on ^94,95,96Mo at n_TOF and GELINA

The n_TOF Total Absorption Calorimeter for neutron capture measurements at CERN

The n_TOF Collaboration has built and commissioned a high-performance detector for ðn;gÞ measurements called the Total Absorption Calorimeter (TAC). The TAC was especially designed for measuring neutron capture cross-sections of low-mass and/or radioactive samples with the accuracy required for nuclear technology and stellar nucleosynthesis. We present a detailed description of the TAC and disc...

Neodymium neutron cross section measurements.

Neutron capture and transmission measurements were performed by the time-of-flight technique at the Rensselaer Polytechnic Institute LINAC using metallic neodymium samples. The capture measurements were made at the 25-m-long flight station with a 16-segment NaI(Tl) multiplicity detector, and the transmission measurements were performed at 15 and 25 m flight stations with a 6Li glass scintillati...

Measurements of the neutron - proton and neutron - carbon total cross section from 150 to 800 keV

Total Cross Section Measurements in γp and γp at HERA

Measurements of the total cross section for real and virtual photons on protons at center-of-mass energies in the range from 20 GeV to 270 GeV with photon virtualities up to 5000 GeV are presented. For real photons this cross section can be described by Regge-motivated models while for virtual photons perturbative QCD can be applied. The measurements of the two HERA collider experiments ZEUS an...

The nucleosynthesis of heavy elements in Stars: the key isotope 25Mg

We have measured the radiative neutron-capture cross section and the total neutron-induced cross section of one of the most important isotopes for the s process, the 25Mg. The measurements have been carried out at the neutron time-of-flight facilities n_TOF at CERN (Switzerland) and GELINA installed at the EC-JRC-IRMM (Belgium). The cross sections as a function of neutron energy have been measu...
