AB  - Laser cooling of Li-like O⁵⁺ ion beams with an relativistic energy of 275.7 MeV/u was achieved for the first time at the heavy-ion storage ring CSRe in Lanzhou, China [*,**]. In the experiment, a CW la-ser system with a wavelength of 220 nm was used to interact with the closed 2s1/2-2p1/2 optical transi-tion of O⁵⁺ ions. In order to cool the relativistic ion beams with only one counter-propagating CW laser, the ion beams were bunched by applying a sinusoidal voltage to the RF-buncher system. The relative longitudinal momentum spread dp/p of laser-cooled ion beams reached 1×10⁻⁶. The O⁵⁺ ions are of the highest charge state and highest beam energy that have ever been cooled by laser cooling method. We will present the very recent experimental results on this COOL 2019 workshop. Based on this successful laser cooling experiment, the precision laser spectroscopy experiment of O⁵⁺ ions is in preparation at the CSRe. A new optical detector is under design and will be installed at the CSRe to measure the forward-emitted fluorescence by the laser-excited O⁵⁺ ions [***,****]. The high voltage of the electron cooler will be precisely calibrated to determine the beam energy. Precision laser spectroscopy of O⁵⁺ ions to measure the transition energy of 2s1/2-2p1/2 and 2s1/2-2p3/2 is foreseen, and the relative accuracy could reach 1×10⁻⁵.
