The problem is that temperature is more or less isotropic, but one would like the stimulation to occur along/orthogonal! to the main (D-D) axes. - again the same / temperature is isotropic but SOME nuclei move along necessary directions (quasi- one dimentional system) I fulfill the evaluation.
The critical radius of two 2pm corresponds roughly to 1keV, what is close to the kinetic reaction energy needed for D-D fusion.- so... we have possbility of the reaction due to the QUANTUM system properties. nobody knows why quantum mechanica is correct.
Thus my recommendation as a next step: Just assume you see a plasma. Assume an electrical potential in the p orbit axes and calculate the plasma-frequency needed (to drive the Alfven sheer wave) from the given lattice constants. we treat nuclei as gas in the article for evaluation of amount of reaction acts- but gas of NEUTRAL particles due to quantum effects I decide equation no more
