We consider now the difficult problem of hydrogen delocalisation inside the lattice of deep electrostatic holes. As delocalisation depends on the occupancy by the protons of highly excited states of the well, this configuration must be energetically advantageous. It then becomes clear that collective phenomena must come into play as, otherwise, the hydrogen nuclei (H+, D+ or T+) could not avoid going into the ground state. The many-body interactions of the hydrogen nuclei must therefore be able to supply the energy required to raise the nuclei to highly excited states of oscillation. It is again evident that this cannot be achieved through short-range forces, thus providing another clear illustration of the inadequacy of conventional theories. On the other hand, the superradiant plasma of hydrogen nuclei considered elsewhere  leads immediately to such highly excited states of the oscillating nuclei by virtue of the superradiant behaviour of the ideal plasma: the highly excited states of the oscillating nuclei compensate their high kinetic energy by the interaction energy with the coherent superradiant electromagnetic field. If this is kept in mind, then one can readily understand the odd properties of H in Pd: thus the high diffusion coefficients reflect the «quasi-free» character of the hydrogen «band» in the lattice of deep holes; the inverse isotope effects of the diffusion coefficients and of the critical temperatures for transition to the superconducting states are due to the bosonic character of D+ as opposed to the fermionic character of H+ and T+, the Pauli principle restricting the configuration space of H+ and T+ but not of D+ . Finally, the high chemical potentials are a likely consequence of the formation of clusters in the size range of a few microns, the size of the coherence domains of hydrogen plasmas . A further aspect of the superradiant behaviour of these systems is referred to in sect. 5.
Ever before polariton condensation is discovered, M Fleischmann posited that such a condition must have existed in the LENR reaction. Also a condensate of a micron sized cluster (aka EVO) that forms a coherent domain is the active factor in the reaction.
How was this original thinking about LENR reaction theory of M Fleischmann lost or ignored over all these many years?
