- But nothing new is being proposed here. This is just simple
- Compton "agitation" by the incident gammas. Even if no other
- process occurs, we ought to expect the Co60 gamma rays to
- knock things around a bit. I believe you said something to
- the same effect before -- the incident gammas *must* be
- doing something, some secondary effects are *required* by the
- situation.
-
- And going to the hypothetical interaction, the "neutron exchange"
- is still a "virtual" process because the input energy is
- insufficient to produce a free neutron on its own accord. The
- energy is "borrowed" from the excess of the Pd neutron capture --
- implying close proximity and nearly simultaneous neutron
- emission and capture.
-
- If I understand it, there are two ways to make tunneling more
- probable. One is to make some form of energy available so that
- the reaction doesn't have to borrow as much from the Bank of
- Uncertainty. The other way is to make the tunnel very short.
-
- Comptom agitation makes the tunnel short. Is there reason to
- doubt that 1-2 MeV kinetic deuterons can have nuclear relations
- with Pd's? Even if the probability is low for any given
- approach, there is a heck of a lot of ricocheting going on.
- (I know, for instance, that air molecules at standard temp and
- pressure collide 10^9 times per second, and their kinetic
- energy is in eV rather than MeV!)
-
- And finally, as someone else pointed out, deuterons are oblong,
- and therefore at a minimum, 50% of the time, they will approach
- the Pd nucleus neutron first. Add the repulsive force acting
- only on the proton, and you have a tendency for the deuteron to
- rotate neutron first toward the target Pd nucleus.
-
- The deuteron neutron can get closer to the Pd than the deuteron
- proton, which should enhance tunneling. And at some optimum
- kinetic input energy, should slow down, stop and reverse -- that
- is, hang around for a bit before zooming off from the repulsive
- force if capture didn't yet occur.
-
- This deceleration force is felt by the proton and transmitted
- to the neutron thru the internal nuclear forces. But it is an
- additional strain on the nucleus. No? Like stopping fast with
- a box on the hood of your car. The car stops but the box keeps
- going.
