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.
WebThe isomeric shift (also called isomer shift) is the shift on atomic spectral lines and gamma spectral lines, which occurs as a consequence of replacement of one nuclear isomer by another. It is usually called isomeric shift on atomic spectral lines and Mössbauer isomeric shift respectively.
