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 relativisticions in storage rings, high-power lasers with wavelengths in the visible range or longer can be used to achieve high excitation rates ofisomers.
The significantly reduced isomeric-state lifetime corresponds to a much higher excitation rate for direct resonant excitation. Importantly, we propose electric dipole transitions changing both the electronic and nuclear states that are opened by the nuclear hyperfine mixing. We suggest using them for efficient isomer excitation in Li-likeions, via stimulated Raman adiabatic passage or single-laser excitation.
