Thanks for your thoughts and suggestions, Mauro. - I will check into Beene's posts on the topic.
One last question I wonder about is whether any certain symmetry in an isomeric nucleus insures that a decay to ground state will cause emission of multiple less energetic quanta in order to respect that (perhaps, radial or spherical) symmetry.
