   The 'thorium transition', which has been sought after for decades,
   has now been excited for the first time with lasers.
   This paves the way for revolutionary high precision technologies,
including nuclear clocks

 
I wonder what the Q value for stimulated nuclear emission is?

They state a centre frequency of roughly 2 PHz and a decay time
of 630s, which would put the Q in the 1e19 ballpark. Prodigious.
No wonder it was hard to find.

It's the only atomic kernel transition with any degree of coupling to
electromagnetic radiation.  This will be orders of magnitude better
than such as lattice clocks.
