Fine-structure constant sensitivity of the Th-229 nuclear clock transition

Abstract Nuclear laser spectroscopy at the 10−12 precision level (Nature 633.8028 (2024): 63–70) determined the fractional change in the nuclear quadrupole moment of 229Th upon excitation, ΔQ 0/Q 0 = 1.791(2)%. Such high-accuracy nuclear parameters enable stringent tests and refinement of 229Th nucl...
