I'm not looking for the simplistic Lorentz contraction answer of zero.  It
takes a finite interval of time for an atomic electron to emit a photon,
and l = c t.  Thanks.

P.S.  I saw the answer to the question "What is the smallest known particle
at present?".  I think the answer would probably best refer to the
particle's cross-section: the neutino.What is the smallest known particle
at present?
