“Lovely gammas” or “Rossi effect” comes in my mind
As for lovely gammas .. it was never meant to be a technical term
and was never written in a technical paper.
its quite appropriate for a blog or fora with a mixed ability readership
for me it meant that the gamma readouts from the nuclear isomers
were regarded with great affection by Russ George.
Who would sign off on a technical paper as Forty-Two?
