Based on these new findings, 'NuQuant' aims to excite the thorium-229 nucleus by laser spectroscopy. For this purpose, a novel cw laser system at a wavelength of 150 nanometres is to be developed, which will then be used for spectroscopy. After successful excitation, the experiment will be further developed into a nuclear clock based on internal conversion (IC). This will transfer existing quantum technological tools to the atomic nucleus domain to open up the exciting new field of nuclear quantum optics.
