Neutron capture cross section of (90)Zr : Bottleneck in the s-process reaction flow
(2008-03)
The neutron capture cross sections of the Zr isotopes have important implications in nuclear astrophysics and for reactor design. The small cross section of the neutron magic nucleus (90)Zr, which accounts for more than ...
176Lu/176Hf : A sensitive test of s-process temperature and neutron density in AGB stars
(2008-01-20)
The s-process branching at A (176) has been analyzed on the basis of significantly improved experimental cross sections. This work reports on activation measurements of the partial (n, gamma) cross section of Lu-176 feeding ...
The measurement of the (206)Pb(n,gamma) cross section and stellar implications
(2008-01)
The neutron capture cross section of (206)Pb has been measured at the CERN n_TOF spectrometer using a setup of two C(6)D(6) detectors. In the energy interval from 1 eV to 600 keV the cross section is dominated by resonances, ...
