What is it about?
Very cold neutrons (VCNs) are important and rare resources for fundamental physics. The community keeps seeking novel moderator materials to improve the production of VCNs. Paramagnetic oxygen systems appears to be potential candidates and the theoretical framework has been established by O. Zimmer. This work provides a physical model combing neutron-nucleus and magnetic neutron scattering to calculate neutron spectra for paramagnetic materials, highlighting the potential use of O2-containing fully deuterated clathrate hydrate for the VCN production.

Why is it important?
This work combines magnetic neutron scattering and neutron-nucleus scattering for paramagnetic O2-containing systems, making it possible for predicting VCN production through Monte Carlo simulations.
Perspectives
In this work, a phenomenological model is adopted to explain the magnetic peak broadening above 20 K. It will be very exciting to dig into this phenomenon with further theoretical and experimental study!
