This is a follow up of #103 presented by @chlavell, and might be of interest to @ameliajo. I tried to recreate the evaluation for solid methane in ENDF/B-VIII.0 using a...

Elastic distributions were created but not used. Fixes #2225

After some discussion with @paulromano we cleaned up this version of OpenMC with support for [NCrystal](https://github.com/mctools/ncrystal). NCrystal is a software library that provides low energy neutron physics to Monte Carlo...

I think I came across a bug. [Here](https://github.com/openmc-dev/openmc/blob/cbd8376238a71c36a57385df4c18471d5a785d64/openmc/data/thermal.py#L733) and [here](https://github.com/openmc-dev/openmc/blob/cbd8376238a71c36a57385df4c18471d5a785d64/openmc/data/thermal.py#L736) the elastic distributions are assigned to "dist", but [here](https://github.com/openmc-dev/openmc/blob/cbd8376238a71c36a57385df4c18471d5a785d64/openmc/data/thermal.py#L745) the elastic reaction is created with "distribution". It is an easy...

This is something we have been discussing with @zoeprieto, @inti-abbate and @norberto-schmidt. Maybe @ebknudsen has something to comment too. In the current implementation of file sources (both in HDF5 or...

In connection with #176, perhaps it would be useful to have the atomDB as an external file (could be a simple csv file). Then bound atom cross sections and abundances...

Currently materials in NCrystal are represented as a system of atoms. At high energies, the cross section goes to the free atom cross section that can be computed from the...

It would be useful if the DI_VDOSDebye provides an analyseVDOS() method. That way DynamicInfo.analyseVDOS() would work whether it is a DI_VDOS or DI_VDOSDebye object. Maybe it would also be better...

As we discussed, when you create an NCMATComposer object from a CIF file, it can be a bit confusing that the labels are not elements even for simple cases: ```...

Coherent scattering at high incident energies can be approximated by incoherent scattering, by means of replacing the sum over reciprocal space points with an integral (see, for instance V.F. Turchin,...
