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

The high-resolution measurement system CARME (CRYRING Array for Reaction Measurements) was used to detect the reaction products generated

A special beam-coolingsystem will play a crucial role here, as it will keep the speed of the circulating particles extremely [...] nucleus now contains an additional proton and has thus become the next-heavier element in the periodic system. Neutron capture and decay take place in a multiple and varying interplay of reactions. This process [...] looking for. It is more than 100 metres long. With the help of magnets that weigh several tonnes, the system will sort the exotic nuclei according to their charge and mass. This will enable the scientists
