Recently, an international research team has carried [...] spectroscopy measurement on helium-like uranium, the simplest and heaviest multi-electron atomic system. Dedicated Bragg crystal spectrometers were constructed and mounted at the gas-jet interaction chamber

Thanks to the flexibility of the high-frequency systems of SIS18, this novel operation mode could be realized by an appropriate extension of the software [...] number of steps still need to be taken. For example, the process is to be combined with electron cooling in order to generate high particle densities. In this context, theoretical studies on the interactions
