The radius of a nucleus is approximately (1.5 fm) x A^1/3 and a
crude estimate of the average kinetic energy of a nucleon is about
8 MeV. Figure it out for 3He. You have a radius of that's a factor
of 10^4 too big.

Why? There's no point, since (1) acceleration and velocity aren't
good quantum numbers anyway, so the velocity and acceleration are
only of heuristic value, (2) the actual numbers would vary widely
depending on the exact atom or nucleus in question, (3) the only
velocity eigenvalue of the dirac equation is `c'. Any other velocity
is really just an expectation value of the zitterbewegung. (4) Since
an electron (or nucleon) which is in an eigenstate, is in a stationary
state, the velocity doesn't make sense as anything but an analogy,
and only then, when the analogy is valid.

Unless ``L'' means angular momentum, pick another letter - preferably
one that isn't ubiquitously associated with a specific quantity.
