Abstract

The interface theory of cold fusion is a variant of Ion Band State (IBS) Theory.1 It models Bloch symmetry deuterons in a 2-dimensional metal lattice instead of the 3-dimensional metal lattice first used. Both IBS variants recognize that the required lattice symmetry has limited extent, with the reactive deuterons being bound inside a closed volume like a box. The reactive deuterons are confined within classical turning point boundaries, while within the box their density distributions are modulated by a lattice array potential. Strictly speaking, the IBS fusion theory is a many-body theory. Nuclear dd fusion is one of several LENR processes. Some LENR processes do not require many-body ions and support room temperature nuclear reactions using light ions in single-particle Bloch geometry. For example, the decay of metastable single-body Bloch-function 8Be seems to be the source of MeV alphas in Oriani's light/heavy water electrolysis, and in several co-deposition electrolysis CR39 studies, as described in ICCF14 Abstracts.2 The Oriani MeV alphas are side products of both light water and heavy water electrolysis, using either Pd or Ni cathodes, as shown in highly repeatable tests. Bloch 8Be is likely the nuclearly reactive component in the final step of the Iwamura et al. transmutation studies.3 Despite differences, all LENR systems seem to share some essential physics.
