We describe our experiments towards the resonant laser excitation of the 8.3 eV nuclear transition in 229Th with the motivation to develop a highly accurate nuclear optical clock for metrology and tests of fundamental physics.

Toward a $^{229}$Th nuclear clock, we performed laser spectroscopy of the triply charged $^{229}$Th isomer ($^{229\rm{m}}$Th$^{3+}$) in an ion trap. The $^{229\rm{m}}$Th$^{3+}$ ions were obtained as a decay product of $^{233}$U. We determined the hyperfine constants of the electronic state of $^{229\rm{m}}$Th$^{3+}$ and derived the magnetic dipole and electric quadrupole moments of...
