  We first show a possible mechanism to create a new type of nuclear fusion,
thermal resonance fusion, i.e. low energy nuclear fusion with thermal resonance
of light nuclei or atoms, such as deuterium or tritium. The fusion of two light
nuclei has to overcome the Coulomb barrier between these two nuclei to reach up
to the interacting region of nuclear force. We found nuclear fusion could be
realized with thermal vibrations of crystal lattice atoms coupling with light
atoms at low energy by resonance to overcome this Coulomb barrier. Thermal
resonances combining with tunnel effects can greatly enhance the probability of
the deuterium fusion to the detectable level. Our low energy nuclear fusion
mechanism research - thermal resonance fusion mechanism results demonstrate how
these light nuclei or atoms, such as deuterium, can be fused in the crystal of
metal, such as Ni or alloy, with synthetic thermal vibrations and resonances at
different modes and energies experimentally. The probability of tunnel effect
at different resonance energy given by the WKB method is shown that indicates
the thermal resonance fusion mode, especially combined with the tunnel effect,
is possible and feasible. But the penetrating probability decreases very
sharply when the input resonance energy decreases less than 3 keV, so for
thermal resonance fusion, the key point is to increase the resonance peak or
make the resonance sharp enough to the acceptable energy level by the suitable
compound catalysts, and it is better to reach up more than 3 keV to make the
penetrating probability larger than 10^{-10}.
