there is still the traditional Coulomb barrier that results from this Coulombic assumption to be tunnelled thru
which presumptively is unlikely for two D(O) nuclei
which is why he needs a negative Muon..?
There are two possible fusion causes IMHO:
1) A changing spinning state from s= 2 to s=1 initiated by a laser pulse. According to Holmlid's data this would cause H(0) nuclei to become close enough (0.56 pm) to fuse.
2) Negative muons, initially generated from cause 1)
Holmlid is carefully avoiding the word 'fusion' here. He probably needs more verifications to be a bit more determined.
And, indeed, his analyses are based on conventional Quantum Physics.
I would love to see him giving feedback on Wyttenbach papers. But I don't think that is going to happen soon.
