Formation of condensed metallic deuterium lattice and nuclear fusion

It was confirmed that nanometer-sized metal powder (atom clusters or simply clusters) can absorb an extremely large amount of deuterium/hydrogen atoms more than 300% against the number density of host metal. Within such clusters, the bonding potential widely changes from the center region to peripheral ones, so that the zig - zag atom-chains are always formed dynamically around the average position of atoms and the degree of filling up of the constituent atoms for the fcc type metal reduces to about 0.64 from 0.74 in bulk metal, i.e., vacant space increases to 0.36 from 0.26. As a result, a large amount of deuterium/hydrogen atoms are instantly dissolved into such host-clusters at room temperature. Furthermore, "metallic deuterium lattice" (or hydrogen one) including locally the "deuterium-lump" With the ultrahigh density is formed with body centered cuboctahedral structure which belongs to a unit cell of the host lattice, while such event cannot be realized at all within bull, metals. It seems that nuclear fusion in solid ("solid fusion") takes place in the highly condensed "deuterium-lump" inside each unit cell of the "metallic deuterium lattice" (or mixed hydrogen one) which is formed inside each cell of the host metal lattice. It is considered, therefore, that each unit cell of the host lattice corresponds to minimum units of "solid fusion reactor". In order to achieve "solid fusion", just the generation of the ultrahigh density "deuterium-lump" (simply "pycnodeuterium-lump") coagulated locally inside unit cell of the host lattice and/or the highly condensed metallic deuterium lattice should be an indispensable condition.
