“…The calculated cross sections were obtained in the same manner as for tin. As can be seen from Figure 3, the calculated total cross sections, including 2200 = 5.08 b, are in excellent agreement with the experimental total cross section measurements from Vertebnyj [24] (EXFOR entry 40294002) and Palevsky [25] (EXFOR entry 11663002). The coherent elastic component is negligible, while the incoherent elastic component is dominant.…”

In this work we present NJOY+NCrystal, a tool to generate thermal neutron scattering libraries with support for coherent and incoherent elastic components for crystalline solid materials. This tool, which is a customized version of NJOY, was created by modifying the nuclear data processing program NJOY to call the thermal scattering software library NCrystal, and includes a proposed change in the ENDF-6 format to store both the coherent and incoherent elastic components. Necessary changes to enable this format in NJOY, as well as to sample it in the OpenMC Monte Carlo code, are detailed here. Examples of materials that are coherent-dominant, incoherent-dominant, and mixed elastic scatterers are presented, as well as the creation of novel libraries for MgH 2 and MgD 2 , that are under consideration as advanced neutron reflectors in the HighNESS project at the European Spallation Source. NJOY+NCrystal simplifies greatly the process to generate thermal scattering libraries (TSL) and this is exemplified with 213 new and updated TSL evaluations.

“…In addition to the contribution from the s~ reaction, transitions associated with neutron capture by sW, carbon, and chlorine were also present with significant intensity. The capture rate for the 5~ reaction may then be inferred by taking into account the relative isotopic abundances and cross-sections for the two reactions [1]. The energy and relative intensity of each 7 ray indicated in the spectrum was deduced from the position and area of the corresponding peak, referenced to the well-known nitrogen spectrum [13].…”
