Hi,
I just read about an interesting characteristic of the nucleon-nucleon
interaction (e.g., the scattering of a proton with a neutron or a proton
with a proton or a neutron with a neutron). I wonder whether this
characteristic is behind what we've been referring to here as "neutron
tunneling" o

My initial thought was that the change would result in a very short-lived

The endothermic part is problematic. That suggests that 7Li is not
involved. I wonder which relevant reacti

Yet another possibility -- the pion exchange happens simultaneously with
the decay of the light isotope to stable daughters, s
If I put on my Don Hotson hat and *-try-* to consider his description of
the proton, neutron, and the strong force, could it provide some insight?
Hotson considers that protons and neutrons are composed of epos, in an
orthogonal condensate in 10 dimensions. There are no quarks - just the
electron-p

Possibly. It seems related. It seems like an implication would be that we
would have to set aside pion exchang
Pions are produced by the vacuum. If the vacuum can be excited, the strong
force can be modified through the influence of the vacuum on pion
production. Everything emerges through the vacuum. The vacuum is
fundamental.

I've worked out a simple model, and here are some reactions:
$ python scripts/reactions.py "Li+Cu, Li+Fe, Li+Ni, d+Cu, d+Fe, d+Ni, d+Li"
--model pion-exchange
d + 61Ni → 2·p + 62Ni + 1082 keVn-transfer, stable
d + 57Fe → 2·p + 58Fe + 531 keV n-transf

This turns out not to have been true. A followup check indicated that

Hi,

You have a bug in your program. Charge needs to conserved.

Before Robin corrects my numbers, I have fixed them myself, and, re-running
the same scenarios, the reactions are, without exception, endothermic!
Even taking into account subsequent decays. (There's something mysterious
in that.)
I guess that's one way to disqualify a potential theory. My since

Hi Eric,
Try starting out with radioactive nuclei, and ending up with stable nuclei. That
should swing the tide in your favour. Often removing a neutron from an unstable
nucleus will make it stable, and adding a proton to anoth
