Measurements of the 90,91,92,94,96Zr neutron capture cross-section at n_TOF

The neutron capture cross sections of 90,91,92,94,96Zr, which play a key role for the determination of the neutron density in the He burning zone of the Red Giant stars, were measured over the energy range from 1 eV to 1 MeV at the spallation neutron facility n_TOF at CERN. Based on these data the c...

Sumario:The neutron capture cross sections of 90,91,92,94,96Zr, which play a key role for the determination of the neutron density in the He burning zone of the Red Giant stars, were measured over the energy range from 1 eV to 1 MeV at the spallation neutron facility n_TOF at CERN. Based on these data the capture resonance strength and the Maxwellian-averaged cross section at 30 keV were calculated.
