As their names counsel, protons Possess a constructive electrical cost, though neutrons are electrically neutral—they have no demand; All round, then, the nucleus provides a favourable charge.
A thin film using a dry precursor of thorium-229 shows exactly the same nuclear excitation since the crystal, but its cheap and radioactivity, and lesser sizing mean its production could be much more very easily scaled up to produce more compact, less costly, a lot more portable atomic clocks.
