The main point I’m making is that it is worth keeping in mind a broader range of calculation methods for identifying potential catalysts for dense H formation...
I have calculated dense hydrogen states based on special relativity and the assumption that such states result from the physics of phats. The equation for energy of phats of hydrogen is E=(13.58378925 eV)n2. For relativity we have L/L0=m0/m=delta t0/delta t = Lorentz factor. I used the volume of hydrogen at the n=1 state as 1.5 times the Bohr radius, 80,000 fm =L0. Then when weak isospin causes the neutron likeness to approach 100%, the apparent radius is 1.4 fm = L. This is based on the formula of the value of nuclear radius. Energy of the "bare" electron in bonded relationship to nucleus manifests as relative mass of the antineutrino. The mass of the anti-neutrino is very small, so small that delta m at n=240 is the mass energy difference between the proton and the neutron rest mass = 0.7824260693 Me V. You can do the calculation/ fitting to get a best fit. I gave you fitted value of E at n=1 above. That value is the best fit at n=240 to 0.7824260693 Me V. You can calculate from the relationship of the Lorentz factor the value of rest mass of the anti-neutrino. It is about 0.109 eV. What I am describing is a state is in weak isospin space. The overall effect is as follows: the atomic radius decreases to the radius of a neutron; the state's decay time increases to that of a neutron free of the atomic nucleus and the relative mass of the antineutrino approaches the mass difference of the proton and the neutron.
For a more analysis of how LENR happens on the above basis see my other posts elsewhere in this forum.
In an EVO the same thing happens. The "bare" electron accesses weak isospin space. The energy which causes rotation in isospin space (from electroness to antineutrioness) cause the relative mass increase in antineutrinos etc as above for a hydrogen atom but without a nucleus. The cluster of electrons happens because the anti-neutrinos cause the effect of special relativity as above. Hence, a kind of artificial gravity (one based on relative mass not rest mass) pulls the electrons into a cluster in opposition to coulomb repulsion between electrons. You may find it fun to guess what is the size of bare electron which accesses the n=1 state in weak isospin space? Obviously, its a function of rest mass of the antineutrino. So, one might use energies as above. But what one needs is an accurate measure of size of an EVO relative to number of electrons in a cluster (EVO). From which one could also calculate half-life of the "bare" electron which access weak isospin space. Please feel free to help.
