Abstract:
Nuclear masses are indispensable ingredients in numerous physics applications ranging from nuclear structure physics, where, e.g., the shell closures and nucleon correlation energies can be studied by accurate mass measurements, via the nuclear astrophysics, where the masses of nuclei far from the valley of β-stability determine the pathways of, e.g., rp-and r-processes of nucleosynthesis in stars, to tests of the standard model and fundamental interactions, where, e.g., the very-accurate masses of parent and superallowed β-decay daughter nuclei serve as one of inputs for the checking of the unitarity of the CKM quark-mixing matrix. In this review we focus on recent direct mass measurements conducted with storage rings and Penning trap mass spectrometry. Although these measurements have a broad impact, we restrict our discussion on two topics, namely nuclear astrophysics and neutrino physics.
