| Zusammenfassung | 229Th with a low-lying nuclear isomeric state is an essential candidate for a nuclear clock as well as many other applications. Laser excitation of the isomeric state has been a long-standing goal. With relativistic 229Th ions in storage rings, high-power lasers with wavelengths in the visible range or longer can be used to achieve high production rates of 229Th isomers. This can be realized through either direct resonant excitation, excitation via an intermediate nuclear state, or excitation via an intermediate electronic state, facilitated by the tunability of both the laser-beam and ion-bunch parameters. Notably, the expected nuclear hyperfine mixing effect in H- or Li-like 229Th ions offers novel opportunities for exciting thorium isomers. In the direct resonant excitation scenario, the significantly reduced isomeric-state lifetime in H- or Li-like 229Th ions would correspond to much higher excitation rates compared to bare thorium nuclei. We also present the possibility of exciting thorium isomers via an electronic excited state in Li-like 229Th ions, where Stimulated Raman Adiabatic Passage as well as single-laser excitation can be implemented. Finally, we discuss schemes for probing produced isomers utilizing nuclear or electronic transitions, through which the isomeric-state energy could be determined with orders of magnitude improvement in precision compared to the current value. The schemes proposed here for 229Th could also be adapted to studying low-energy nuclear states in other nuclei, such as 229Pa. The present discussion shall facilitate the relevant experimental efforts as well as affect the concepts of future trapping and storage facilities. |
