Ultra-cold Neutron Production in Anti-ferromagnetic Oxygen Solid

الأصل · EN

Spin waves, or magnons, in the anti-ferromagnetic α phase of solid oxygen provide a novel mechanism for ultra-cold neutron (UCN) production. Magnons dominate the energy exchange mechanisms for cold neutrons and UCN in solid α-oxygen, much in the same way as do phonons in solid deuterium superthermal UCN sources. We present calculations of UCN production and upscattering rates in S-O₂. The results indicate that S-O₂ is potentially a much more efficient UCN source material than solid deuterium.
