- a single very tiny region of the lattice for the final focusing of energy.

- Not normally. You've got the metallic equivalent of an electron gas, and
- unless disciplined in some curious fashion it will behave like most gases --
- chaotically.

- I have been boning-up on the stochastic acceleration literature that I
- posted a reference to in this group as a possible acceleration
- mechanism for light-emitting cavitation. (I was not thinking directly
- in terms of solid-state fusion at the time.) However, in my digging
- around, I discovered that there was an acceleration mechanism
- postulated by Fermi which entailed accelerations via random fields.
- (Fermi was seeking a mechanism for cosmic rays.) Ulam made a
- simplified model of this. It consisted of a particle moving between
- two walls -- one of which is periodically vibrating. Hmm, lets see --
- Fermi (electron) gas, lattice vibrations (phonons), periodic
- potentials (crystal lattice) anyone?
-
- Just some solid state thoughts,
