“…There are measurements by Wisshak et al [16] in the unresolved resonance region and by Shamu et al [43] from 0.7 MeV up to 14 MeV, and a single-energy point by Djumin et al [44] at 14.2 MeV. In addition, there is the measurement of the elastic angular distribution at 7.0 MeV by Haouat et al [45]. These data allow to derive parameters of the optical model potential within acceptable margins.…”

“…In order to ensure smooth cross sections, we disregarded several measurements which deviated too much, see 145,148 Nd. In the fast neutron region, our evaluations normally considered the experimental data on the natural neodymium [46,49,48,50,15,47] We started our evaluation with adjusting the optical model parameters to reproduce total cross sections [43] and elastic angular distributions [45] Nd were subsequently used as an initial guess for the remaining neodymium isotopes. They were adjusted to reproduce measured data for the total cross sections on nat Nd [46,49,48,50,15,47] and isotopic Nd [44], and angular distributions of the elastic scattering on isotopic Nd [45].…”

“…Although these data do not allow to address individual isotopes, they provide an overall energy dependence that can be refined by referring to isotopic measurements. For instance, the elastic angular distributions measured by Haouat et al [45] can be used to adjust OMP to describe interaction of neutrons with 142,146,148…”

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.

In this paper, we construct a new phenomenological isospin dependent global neutron-nucleus optical model potential. Based on the existing experimental data of elastic scattering angular distributions for neutron as projectile, we obtain a set of the isospin dependent global neutronnucleus optical model potential parameters, which can basically reproduce the experimental data for target nuclei from 24 Mg to 242 Pu with the energy region up to 200 MeV.
