Because the relatively small neutron capture cross sections of the zirconium isotopes are difficult to measure, the results of previous measurements are often not adequate for a number of problems in astrophysics and nuclear 0556-2813/2010/81(5)/055801 (9) 055801-1 ©2010 The American Physical Society G. TAGLIENTE et al.PHYSICAL REVIEW C 81, 055801 (2010) technology. Therefore, the 92 Zr(n,γ ) cross section has been remeasured at the CERN n TOF facility, providing a set of improved parameters for 44 resonances in the neutron energy range up to 40 keV. With this information the cross-section uncertainties in the keV region could be reduced to 5% as required for s-process nucleosynthesis studies and technological applications.

“…The data acquisition system was based on fast digitizers operating at 10 8 samples/s [18]. The data from the digitizers were reduced by a zero-suppression routine and the remaining signals were stored for off-line analysis of the deposited energy in the detectors and the respective time of flight (TOF).…”

Abstract. The neutron-induced fission cross-section of 241 Am has been measured relative to the standard fission cross-section of 235 U between 0.5 and 20 MeV. The experiment was performed at the CERN n TOF facility. Fission fragments were detected by a fast ionization chamber by discriminating against the α-particles from the high radioactivity of the samples. The high instantaneous neutron flux and the low background of the n TOF facility enabled us to obtain uncertainties of ≈ 5%. With the present results it was possible to resolve discrepancies between previous data sets and to confirm current evaluations, thus providing important information for design studies of future reactors with improved fuel burn-up.

“…The combination of the high intensity and wide energy range of the neutron beam with state-of-the-art detectors and the digital data acquisition system available at n_TOF have provided in the last decade a large number of high-quality cross-section data [17,[22][23][24][25] and several key contributions [26][27][28][29][30] regarding the measuring and analysis techniques commonly employed in time-of-flight experiments.…”

The neutron capture cross section of 237 Np was measured between 0.7 and 500 eV at the CERN n_TOF facility using the 4π BaF 2 Total Absorption Calorimeter. The experimental capture yield was extracted minimizing all the systematic uncertainties and was analyzed together with the most reliable transmission data available using the SAMMY code. The result is a complete set of individual as well as average resonance parameters [D 0 = 0.56(2) eV, γ = 40.9(18) meV, 10 4 S 0 = 0.98(6), R = 9.8 (6) (2002)]. The results indicate that a new evaluation combining the present capture data with reliable transmission data would allow reaching an accuracy better than 4%, in line with the uncertainty requirements of the nuclear data community for the design and operation of current and future nuclear devices.
