Seminar topic: “Neutron spin-filter with spin-exchange interaction of 3He nuclei and the atoms of a saturated ferromagnetic”
Speaker: Vadim Skoy
The model of a spin – exchange interaction between the nuclear magnetic moment of 3He and the magnetic moments of electrons in a ferromagnetic is proposed. If a ferromagnetic is saturated an interaction leads to a gradual rising of 3He nuclear polarisation inside a volume surrounded by this ferromagnetic. The conditions for a practical implementation of a neutron spin filter with the polarised 3He nuclei are considered, as well as the variants of its design.
