Melting point 20.4 K, boiling point 23.67 K. A principal fusion fuel in thermonuclear weapons, can also be used for fusion boosting, and in neutron generators. Magnetic Moment: 0.8574 nuclear magnetonsīest nuclear reactor moderator due to high moderating efficiency and extremely low absorption cross section.Due to moderating ability and light weight, used to harden weapons against outside neutron fluxes (especially in combination with Li-6). Widely used in nuclear weapon structural materials (i.e. Lightest possible atom, and consequently the most efficient neutron moderator.
