Nuclear Masses
- Guy Savard (Argonne National Laboratory)
High-precision atomic mass measurements of radioactive nuclides provide a way to determine nuclear binding energies that can be used to benchmark nuclear models. Important information on nuclear structure, e.g., shell gaps and their evolution, pairing effects and isospin symmetry, can be extracted from the ground-state binding energies. In addition, Penning-trap mass spectrometry, and in...
The two-proton radioactivity (2p decay), where two protons are simultaneously emitted during nuclear decay, was theoretically predicted over 60 years ago[1]. In the early 2000s, 2p decay was discovered in very proton-rich nuclei such as 45Fe and 48Ni [2, 3]. The en- ergy level structure and one- and two-proton separation energies (Sp, S2p) are essential to evaluate the two-proton emission...
Mass measurement facilities are extremely important in furthering our understanding of nuclear structure away from the valley of stability, including searching for collective be- haviors and probing the appearance and disappearance of shell closures. TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN) is among the world’s premier precision trapping facilities, with the newly added...
