The atomic nuclei of the chemical elements that make up our world are formed through nuclear processes in stars. Formation probability of different elements can be estimated using nucleosynthesis simulations. Essential input parameters for these simulations are the characteristics of nuclear beta decay, beta decay rates and half-lives. For nuclei located far from the stability, we can determine these values through experiments using radioactive beams. We conduct our experiments at the RIKEN Nishina Center in Tokyo. As part of our project, we determine the characteristics of beta decay in heavier neutron-rich nuclei as well as proton-rich nuclei located on the other side of the valley of stability. The projects have been approved by the RIKEN Program Advisory Committee with a high rating, and researchers of ATOMKI are (co-)spokespersons. These experiments are part of an international collaboration in which the Hungarian research group plays a key role.
