Laser spectroscopy is a powerful tool for studying how structures of ground and isomeric states evolve across the chart of nuclides [1]. By measuring isotope shifts and hyperfine structures we can deduce fundamental properties such as nuclear spins, changes in mean-squared charge radii and electromagnetic moments, all in a model-independent way. Such data are excellent tests for theory,...
In stellar environments nuclei appear at finite temperatures, becoming extremely hot in core-collapse supernovae and neutron star mergers. However, due to theoretical and computational complexity, most model calculations of nuclear properties are performed at zero temperature, while those existing at finite temperatures are limited only to selected regions of the nuclide chart. Recently a...
A novel technique has been developed to measure lifetimes of heavy neutron-rich nuclei, namely 'the reversed plunger'. In heavy neutron-rich nuclei, information on the lifetimes of low-lying excited states is scarce since these nuclei are difficult to populate. Among different reaction mechanisms, multi-nucleon transfer reactions have shown to be the perfect tool to explore such regions....
Recently, some theoretical nuclear structure works have pointed out the relation between the nuclear matrix elements of neutrinoless double-beta decay, a much sought-after nuclear decay that emits two matter particles without antimatter [1,2], and the corresponding matrix elements of double-gamma decay from the double isobaric analog states (DIAS) of the initial double-beta decay nuclei [3,4]....
The Facility for Rare Isotope Beams (FRIB) [1] is a US Department of Energy User facility providing primary, heavy-ion beams with energies up to 300 MeV/u (typically 250 MeV/u for most mid-mass beams). Typical beam intensities are 500 pnA with plans to increase to 20,000 pnA. This capability positions FRIB as a pivotal resource for accessing a broad spectrum of rare isotope beams. Herein, we...
