651. Prevailing triaxial shapes in exotic and heavy nuclei

theory

invited presentation

Shapes of heavy deformed nuclei are discussed from the viewpoint of the Monte Carlo Shell Model with realistic effective NN interactions. The prevailing triaxial shapes then emerge due to the nuclear tensor force, in contrast to the conventional picture of the prolate-shape dominance since 1950's. The triaxiality with $\gamma\sim9^\circ $ arises commonly for rare-earth nuclei around...

spectroscopy

invited presentation

The study of nuclei far from stability is one of the most active and challenging areas of nuclear structure physics. The neutron-proton imbalance in nuclei approaching the dripline(s) affects the detailed impacts of the residual interaction, modifying single-particle energies and potentially leading to altered ground and excited-state properties. In addition, at the very edge of stability,...

astrophysics/nucleosynthesis

invited presentation

Most of the time, stars gain their energy from fusion of the very light left-overs of the Big Bang into heavier elements over long periods of time. The observation of radioactive isotopes in different regions of the Universe is an indicator of this ongoing nucleosynthesis. In addition, short-lived nuclei are often intermediate steps during the nucleosynthesis in stars. A quantitative analysis...
