Now we are back to "stickiness" again. The energy with which D is lodged in the
"anvil" is going to be a fraction of an eV at best. Unless the approaching D has
much much more than this, there isn't going to be an adequately close approach
anyway. This is akin to conventional fusion, and you need something on the order
of 1000-5000 eV to get results. Compared to this, the fraction of an eV of
"sticking" energy is meaningless. IOW it's more a fog than an anvil.

My mistake. I should have said all inertial frames, not all frames. (I normally
don't think about accelerated frames - hurts my brain). ;)
