Mass measurements of the most exotic nuclei and their relevance for nuclear structure — •Timo Dickel1,2, FRS Ion Catcher Collaboration1,2, and TITAN Collaboration3 — 1GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt — 2Justus-Liebig-Universität Giessen, Giessen — 3TRIUMF, Vancouver, Canada
High-performance multiple-reflection time-of-flight mass spectrometers (MR-TOF-MS) developed at Justus Liebig University Gießen have been used for nuclear physics experiments using the FRS Ion Catcher experiment at the in-flight fragment separator FRS at GSI and the TITAN experiment at the ISOL facility ISAC at TRIUMF, Canada. The unprecedented sensitivity and mass resolving powers of these MR-TOF-MS allows to study the nuclear structure and astrophysics at the extremes of the nuclear chart. A wide range of cases will be presented, from investigations of the astrophysical scenario of the r-process to nuclear structure effects like the island of inversion or the shell structure at the outskirts of the nuclear chart.
In addition, the use of these MR-TOF-MS goes even beyond precision mass measurements, e.g., they can be employed to unambiguously identify and analyze ions independent of their decay properties. This enables novel and universal approaches to measure reaction cross-sections, fission yields, half-lives, and branching ratios. Recent highlights and outlook for both experiments at GSI and TRIUMF will be presented.
