Xing Zhong Li's Response to
Nov. 26, 2007 Survey

Question: "Can any of you point to any experiment that shows a match for your theory? If so, can you please provide me with the related papers and identify the specific experiments for me?"

Professor Li, Xing Zhong

Theoretical-Experimental Matches
In response to your e-mail, I briefly summarize as follows:

Theoretical model:

  • Selective resonant tunneling model was proposed in 1995 [1,2] in order to explain the Huizenga’s three puzzles: How is the Coulomb barrier penetrated? Why is there no commensurate neutron emission? Why is there no strong Gamma radiation?
  • Selective resonant tunneling model predicted a long life-time resonance of D-D state in crystal lattice: Life-time ~ Flight-time/(Gamow factor)^1/2. Gamow factor is a very small number.


  • This long life-time implied the possibility of having 3-deuteron fusion reactions in low energy beam-target experiments.
  • Professor Takahashi confirmed the 3-deuteron fusion reactions in 1997 [3]. Indeed Professor Kasagi first discovered 3-deuteron fusion reaction in 1993 [4].


  • Tritium is the product of 3-deuteron fusion reaction.
  • Recently, Dr. T. Claytor of Los Alamos Lab. successfully produced tritium in glow-discharge tube [5] with pure deuterium gas.


  • Dr. T. Claytor has been able to run his glow-discharge tube for several weeks. This implies the possibility of detecting neutrino in the future. [6]
