This paper is the second of a set of 3 papers dealing with the role of coherent partitioning as a common element in Low Energy Nuclear Reactions (LENR), by which is meant cold-fusion related processes. This paper discusses the first step in a sequence of 4 steps that seem to be necessary to explain Iwamura 2-alpha-addition surface transmutations. Three concepts are examined: saltmetal interface states, sequential tunneling that transitions D + ions from localized interstitial to Bloch form, and the general applicability of 2-dimensional vs. 3-dimensional symmetry hosting networks.
