Abstract
The real time exponential decay laws for meta-stable charged particles
are shown to require radiative corrections. The methods employed are
well known to be valid for radiatively correcting Breit-Wigner line shapes.
Radiative corrections contribute substantially to
precision life time measurements of muons and pions when
initially stopped in condensed matter.
