* In this reaction of relatively cold deuterons, gamma emission cannot
proceed, and fusion to deuterium is suppressed in favor of complete
disintegration of protons and neutrons into quarks.
. should read: "gamma emission cannot proceed, and fusion of deuterium to
helium is suppressed in favor of complete disintegration of protons and
neutrons into quarks."
BTW - there is some support for this view - showing up in a paper by
Granados on the photodisintegration of deuterium the within the QCD hard
rescattering model (HRM). According to the HRM, the process develops in
three steps: a photon (in this case, the 24 MeV internalized photon) knocks
a quark from the nucleon; the struck quark rescatters off a quark from
another nucleon; then the energetic quarks recombine into two outgoing
baryons which have large transverse momenta.
This is a stretch. of course . if it were not, someone would certainly have
suggested it before now.
