Description

The increasingly precise knowledge of atomic masses continues to play an important role in our understanding of the nuclear structure as well as the nucleosynthesis of the chemical elements. Developments in mass spectrometry techniques played an important role in overcoming the challenges of measuring atomic masses of exotic nuclei with very short half-lives and accessible only at a handful of accelerator facilities around the world. Despite hosting one of the oldest accelerator facilities, RIKEN joined the development of mass spectrometry for unstable nuclei only in the last decade or so. In this seminar, an overview of the key mass spectrometers developed at RIKEN, namely SHARAQ, MR-TOF-MS and Rare-RI Ring, will be given. The recent achievements of mass measurements in nuclear structure and astrophysics will be presented [1,2,3]. Finally, future opportunities at RIKEN using these devices will be shown.
