In reply to Eric Walker's message of Mon, 22 Sep 2014 22:42:04 -0700: Hi Eric,
On the face of it this sounds reasonable, but real life is seldom so simple. Some deuterons will bounce off lattice nuclei in elastic collisions and head off in completely different directions, so I would expect at least some reactions to produce protons that end up injected into the lattice. Note that at the atomic level material surfaces are often rough. >On Mon, Sep 22, 2014 at 10:33 PM, <mix...@bigpond.com> wrote: > >...but wouldn't you expect 1/2 to fly away from the surface, and half to fly >> into it? >> > >I would expect there to be an anisotropy.
