Atomic nuclei that have same or nearly same amount of neutrons and protons have a key role in understanding underlying structure of nuclei and astrophysical processes like stellar evolution and creation of elements. The key quantity that is needed is their mass enabling, for example, modelling of astrophysical process that is responsible of creation of large fraction of different chemical elements. This project focuses on measuring masses of relevant nuclei up to tin-100, which has 50 neutrons and 50 protons. Existing data on this region is scarce. To access these nuclei and to perform the measurements, two world-leading facilities will be utilized: the Ion Guide Isotope Separator On-Line facility at accelerator laboratory of University of Jyväskylä in Finland and Radioactive Isotope Beam Factory in Riken, Japan.
