“…Nd, 9.722 and 8.747 MeV, respectively. The measurements by Koehler et al [27] in the unresolved resonance range on Nd and those by Okamoto et al [74] and Cheifetz et al [75] of 145 Nd(n,α) at the thermal energy, indicate that (n,α) cross sections below 1 MeV are small but not negligible. When accounting for this region, we attempted to include an expected resonance structure by assuming that the (n,α) excitation function is modulated in the same manner as the total cross sections.…”

Neutron cross sections for a complete set of Nd isotopes, 142,143,144,145,146,147,148,150 Nd, were evaluated in the incident energy range from 10 −5 eV to 20 MeV. In the low energy region, including thermal and resolved resonances, our evaluations are based on the latest data published in the Atlas of Neutron Resonances. In the unresolved resonance region we performed additional evaluation by using the averages of the resolved resonances and adjusting them to the experimental data. In the fast neutron region, we used the nuclear reaction model code EMPIRE-2.19 validated against the experimental data. The results are compared to the existing nuclear data libraries, including ENDF/B-VI.8, JENDL-3.3 and JEFF-3.1, and to the available experimental data. The new evaluations are suitable for neutron transport calculations and they were adopted by the new evaluated nuclear data file of the United States, ENDF/B-VII.0, released in December 2006. 24.10.Eq, 24.60.Dr, 24.60.Gv, 25.40.Fq * Corresponding author.Email addresses: hikim@kaeri.re.kr (Hyeong Il Kim), mwherman@bnl.gov (M.

“…Recently, experimental data for the 143 Nd(n,α) 140 Ce reaction have been measured at energies below 1 MeV [32] and between 4 and 6 MeV [33], and earlier data below 10 MeV are available from [34] and [35]. The calculation of the 143 Nd(n,α) 140 Ce reaction cross section in the statistical model requires the knowledge of the 140 Ce-α potential.…”
