Jones I looked into the issue of variation of amu over the range of elements in the past and found that an interesting rule applied. Only one stable isotope of any of the elements can occupy a certain amu with a few well defined exceptions. All of the other elements and their isotopes with that same amu value would beta plus or minus decay into that central specific one. I assumed that this was due to the low energy cost of beta type decays.
The exceptions were noted for large amu elements and isotopes and appeared to be due to the existence of a local minimum energy state surrounded by higher energy isotopes. In no case did I find a completely stable pair adjacent to each other. Stable means not radioactive since there are a couple of very long lived but nevertheless radioactive matches in amu. I came up with a curve fitting routine that would locate the main central stable amu value for all the elements. The location that yielded a long term radioactive pair happened to be where the exactly calculated value fell extremely close to the center of the two isotopes. I am not sure as to how this behavior can be used to explain any other phenomena, but it certainly is interesting.

This should be "In contrast, B-10 does not keep neon from having an isotope at 20." And yes, there are other reasons why helium has special stability in the periodic table, so this is not a particularly strong metaphor - but it does suggest that there are indeed forbidden isotopes at a few specific atomic mass levels - which are in effect "reserved" by other elements, such as in the case of He-4 which keeps Be-8 from stability. If there were not an LENR connection, this would be the end of the story but there is more. For instance wrt the Rossi effect, 100% of cobalt is amu 59 which seems to be "reserved" by cobalt (element 27). IOW - this isotopic level - amu 59 - belongs to cobalt, even though Co is to the left of nickel in the PT, which is element 28... and nickel's main isotope is Ni-58 - which is one of the few instances in nature where a lighter amu element follows a heaver one (as the main isotope). Notably, Ni-59 decay is gammaless. However, this is not the nickel Mossbauer isotope which is Ni-61. Nickel seems so commonplace, at first ... so few-cents-worth - yet this element has 7 unusually strong physical anomalies, which could relate to LENR and in comparison with other metals is an oddball. The 7 anomalies. It is ferromagnetic, has a Mossbauer isotope, has the heaviest stable isotope (as a % of the most common isotope Ni-58 vs Ni-64), is lower amu than the next lower mass z (the most common isotope is lower amu than Co), has the highest innate stability (Ni-62 has highest binding energy per nucleon of any known nuclide 8.7945 MeV), has an unstable isotope with gammaless decay - and has two adjoining Rydberg levels in electron orbitals. Wow. Could this all be coincidental? What's in a name? The German word "nickel" came from "Old Nick" which was a name for the devil; and the reasons for that historic association are arcane ... but in the modern day context of LENR, where the devil is in the details - let's just say nickel may be our Maxwell's demon. The unification of good and evil, no less?
