The thorium-229 low-energy isomer and the nuclear clock

WebThe nuclear isomeric transition in thorium-229 appears to offer a solution to this problem. Because interactions in the nucleus occur at the MeV energy scale, as opposed to the eV scale in atomic measurements, a nuclear energy level is roughly times more sensitive to any variation in the fundamental constants. WebIf the energy barrier between two conformational isomers is low enough, it may be overcome by the random inputs of thermal energy that the molecule gets from interactions with the environment or from its own vibrations. In that case, the two isomers may as well be considered a single isomer, depending on the temperature and the context.
