calculated, the Q works out to be about 10^8. If you take the frequency
of line and the line width for the Q value, that is.

For atoms and EM radiation, the Q is really high. For the one case I justThis very group had an extended thread on this subject, started by Mr
Beaty as I recall. Nothing he says is remarkable: a short antenna can
be matched with a high-Q tuning network such that it radiates like a
longer antenna. And antannas are reciprocal devices. So a short
receive antenna can be tuned to radiate or gather as much energy as,
say, a half-wave dipole. It just takes a very high-Q matching network;
the smaller the antenna, the higher the Q.
