Ni62 finding looks really mysterious. One interesting finding is that the size 100 micrometers of the Ni62 block corresponds to the secondary p-adic length scale for W bosons. Something deep? Let us however forget this clue.

One can imagine all kinds of exotic solutions but I guess that it is the reaction kinetics **"dark fusion + subsequent ordinary fusion repeated again and again"**, which leads to a fixed point, which is enrichment by Ni62 isotope. This is like iteration. This guess seems to work!

- The reaction kinematics in the simplest case involves three elements.

- The addition of protons to stable isotopes of Ni. One can add N=1,2,... protons to the stable isotope of Ni to get dark nuclear string NiX+N protons. As such these are not stable by Coulomb repulsion.

- The allowed additional stabilising reactions are dark W boson exchanges, which transfer charge between separate dark nuclear strings at flux tubes. Beta decays are very slow processes since outgoing W boson decaying to electron and neutrino is very massive. One can forget them. Therefore dark variants of nuclei decaying by beta decay are effectively stable.

- The generation of dark nuclei and their transformation to ordinary nuclei occurs repeatedly. Decay products serve as starting point at the next round. One starts from stable isotopes of NiX, X=58, 60, 61, 62, 64 and adds protons some of which can by dark W exchange transform to neutrons. The process produces from isotope NiX heavier isotopes NiY, Y= X+1, X+2,.. plus isotopes of Zn with Z=30 instead of 28, which are beta stable in the time scale considered. Let us forget them.

- The addition of protons to stable isotopes of Ni. One can add N=1,2,... protons to the stable isotope of Ni to get dark nuclear string NiX+N protons. As such these are not stable by Coulomb repulsion.
- The key observation is that this iterative kinematics increases necessarily mass number!! The first guess is that starting from say X=58 one unavoidably ends up to the most massive stable isotope of Ni! The problem is however that Ni62 is not the heaviest stable isotope of Ni: it is Ni64!! Why the sequence does not continue up to Ni64?

The problem can be solved. The step Ni62→Ni62+p leads to Cu63, which is the lightest stable isotope of Copper. No beta exchanges anymore and the iteration stops! It works!

- But how so huge pieces of Ni62 are possible? If dark W bosons are effectively massless only below atomic length scale - the minimal requirement - , one cannot expect pieces to be much larger than atomic length scale. Situation changes if the Planck constant for dark weak interactions is so large that the scaled up weak scale corresponds to secondary p-adic length scale. This requires h
_{eff}/h≈ 2^{45}≈3.2 × 10^{13}. The values of Planck constant in TGD inspired mode of living matter are of this order of magnitude and imply that 10 Hz EEG photons have energies in visible and UV range and can transform to ordinary photons identifiable as bio-photons ideal for the control of bimolecular transitions! 100 micrometers in turn is the size scale of large neuron! So large value of h_{eff}/h would also help to understand why large breaking of parity symmetry realized as chiral selection is possible in cellular length scales.
