The intensity and density of the triggering energy supplied to activate the nuclear fusion reaction are key factors to produce a smooth and reproducible initiation of the reaction. We previously proposed and numerically analyzed a scheme to provide high-density optical or electromagnetic energy to fusion-fuel materials by lasers and plasmonic field-enhancement effects, to significantly increase the reaction probability [1–6].
Large degrees of field enhancements, or energy focusing, were observed around metal nanoparticles and nanoshells [1], planar metal surfaces [2,3], metal/oxide interfaces [5], sharp metal tips [4], and metal nanogaps [6]. Strikingly, the field enhancement factors for hydrogen-absorbing transition metals, Pd, Ti, and Ni, can surpass those for noble metals in the microwave region [3,4].
This electromagnetic boosting effect may have unconsciously benefited the experiments reported so far, particularly for the electrolysis-type ones, and its active utilization with proper choices of materials, structures, and operating conditions can improve condensed-matter fusion systems further. Gas-phase experimental research in quest of condensed-matter fusion is underway by using multilayered deuterium-containing Pd plates.
In our experiment, we in particular directly apply a bias voltage across the Pd sample to provide a current injection through Pd, to stimulate the nuclear reaction by Joule heating, also anticipating strong electrodiffusion or electromigration, in addition to the conventional deuterium diffusion induced by pressure/mass-concentration and thermal gradients. We installed multiple kinds of lasers in the gas-phase D–Pd reaction system to irradiate the Pd samples coated with noble metal nanoparticles, as energetic stimulation support, potentially with a boosting plasmonic local field-enhancement effect.
We simultaneously observed a sudden temperature increase with an overshoot and a neutron signal. Significantly, we observed a clear signal of substantial-amount 4He generation from the Pd samples as a shoulder peak on the D2 peak, and a possible 3He signal, via in-situ mass spectroscopy [7].
We also observed a sudden burst of these gas species out of the Pd sample. Our results might indicate a certain anomalous nuclearrelated reaction in the D–Pd system.

“You’re not usually that honest.”
Please cite where I have not been honest.
Just post your exchange with Professor Tanabe, and then we’ll know your question (#7 in this thread) was honestly posed. Easy. Until you do that, you have your answer.
But really, anyone can just look at your posting history here on Free Republic to get all the examples they could stomach.
“He holds an endowed chair at Texas Tech, which last time I checked is a pretty good university. He left one faculty post and got another, better one. Good for him.”
What position? TR has no nuclear programs or facilities and is Tier 2 versus U Missouri Tier 1.
“He left one faculty post and got another, better one.”
At Missouri he was running the show but at TT? Professor.
It’s sad that Wendy O. Williams didn’t live to see this ...
Thanks for having a sense of humor X. Honest, I’m not a troll, just a FRiend trying to lighten the load when I see a train wreck coming.
