Bob,
That distinction is probably correct, although Miley’s version, which is no longer in favor, can be either clusters or singlets, IIRC. In the Lawandy model, the electrons are internalized to the substrate, and a dielectric substrate is required. I am hoping that Meulenberg will address the issue one of these days – of exactly how his Femto or DDL concept is either the same or different from UDH. The semantic problem with calling multiple nuclei a “cluster” is that there really is no 3D agglomeration. The UDD cluster is two dimensional like a film of one atom thickness, and should probably be called an ultra-dense thin film. At least that is the latest Holmlid version AFAIK. From: Bob Higgins Jones, isn't there a distinction between [UDH and UDD] and the [IRH and DDL]? As I understood it [IRH and DDL] are references to sub-ground states for an individual hydrogen atom. OTOH, [UDH and UDD] are condensed matter states of multiple atoms. Did I get this wrong?

These are the same slides used by Ólafsson at the colloquium back in October at SRI, reported here: https://www.mail-archive.com/vortex-l@eskimo.com/msg105372.html Here is the easy link to the slides https://goo.gl/Zlenbp However, even today – the majority of observers in LENR seems to gloss over the main point – which is that although fusion can happen, the bulk of the energy release is in the form of muons (aka meson chain) and is generally lost to the reactor itself (since most of the energy ends up as neutrinos). Even so, there is net gain. The implication is that if properly engineered, the gain will be much higher. In short, “something is accidentally created,” which causes seemingly impossible nuclear reactions (nucleon disintegration) and that something is UDH or UDD – ultra dense hydrogen. George Miley used to call it IRH or inverted Rydberg hydrogen. Now it is simply call UDH or DDL (deep Dirac level). Ultra-dense hydrogen can be the source of all or part of Cold fusion LENR related phenomena. Laser induced fusion in UDH is the most effective way to see the results since it produces muons as the longest-lived species. This is also known as the “meson chain reaction” and the lifetime is several microseconds, so that most of the energy will be deposited as neutrinos many meters away from the reactor – up to hundreds of meters.
