As an alternative to professor Kims offering, I humbly offer this alternative explanation to the origin and possible functionality characterized by the atomic coherence that is required if radiation from the nuclear reactions that makeup the Rossi process are to be suppressed.
First off, the formation of Rydberg matter begins with the production of highly excited alkaline atoms (HEAA) when hydrogen, lithium and/or potassium are heated to high temperatures and pressures enclosed within a gaseous envelope composed primarily of hydrogen gas. Yes, lithium or potassium is the most probable secret element additives that catalyze the formation of Rydberg matter. In all methods currently known to successfully form Rydberg matter; an adjacent surface removes the excess energy released by the condensation of these HEAA. The most efficient process to form this condensate of Rydberg matter clusters so far has been desorption (evaporation) from a solid surface as they seek to minimize their energy, which means that the excess bond energy is deposited in the surface. In more detail, like bosons that can be condensed to form Bose-Einstein condensates, Rydberg matter can be condensed, but not in the same way as bosons. The reason for this is that Rydberg matter behaves like a gas where it cannot be condensed without removing the condensation energy. If this heat removal is not done, ionization of the component atoms occurs. All solutions to this problem so far involve using an adjacent surface in some way, the best being evaporating the atoms of which the Rydberg matter is to be formed from and leaving the condensation energy on the surface. However in the Rossi reactor, the absorption of energy from HEAA is done onto the cold walls of the reaction vessel. This formation of Rydberg condensate matter is a change of state process that will cause Rydberg matter to first form and then to hover very near to the surface of the reaction vessel walls through an electrostatic attraction at the point on the electrostatically grounded reaction vessel wall where it was formed. This condensate then acts to catalyze the Rossi process. Highly excited atoms of lithium or potassium form a condensation template or seed that excited hydrogen atoms use to condense around at the surface of the reaction vessel. Oftentimes, these lithium or potassium atoms might combine and intermix with hydrogen to form a multi- alkaline -element complex variety of Rydberg matter condensate. In the final step of the Rossi process, the coherent wave forms of these many Rydberg atoms that comprise the Rydberg condensate will work in concert through a quantum mechanical summation process to form a combined, entangled and coherent de-Broglie wave form whose wavelengths become sufficiently large to overlap with those of the neighboring nickel quantum wave forms composing the rugged nano-powder coated surface walls of the reaction vessel. The condensate then participates in nuclear fusion reactions at or very near the surface of the reaction vessel of the Rossi reactor. Because of its very large coherent de-Broglie wave form, the effective quantum mechanical range at which this condensate operates may be anywhere up to a few hundred nano-meters centered upon the location of its formation.
