This nuclide is useful for thickness gauge of thin plastics. Due to weak radiation emissions, it is used in safe luminescent displays. It can also manufactured and loaded into weapons (with deuterium) for use in fusion boosting of fission weapons, as the neutron source in neutron bombs and neutron generators for commercial or weapons use. It is produced in place by tritium breeding reactions in thermonuclear weapons. Magnetic Moment: 2.9789 nuclear magnetonsĪ principal thermonuclear fuel, best used in conjunction with deuterium (the D+T reaction is the easiest by far to ignite, as well as one of the most energetic).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.

An appropriate condition for the fission isomeric state is also pointed out. It has also been seen that the sub-barrier fission from the excited state is a slow process. Our results clearly show that dissipation enhances the tunneling rate. The powerful semiclassical quantization technique lifts the degeneracy between the degenerate levels just after tunneling across the barrier. The interaction barrier is calculated by using the asymmetric two-centre shell model and its appropriate parameterization generates the analytical expression for the tunneling probability. The systematics of spontaneous fission in actinides and heavy elements are investigated within the framework of the semiclassical quantization.
