ground-state properties

invited presentation

The heaviest elements are of interest to nuclear and atomic physicists due to their peculiar properties. While nuclear shell structure effects are responsible for their very existence stabilizing them against spontaneous disintegration, the structure of their electronic shells is affected by strong relativistic effects leading to different atomic and chemical properties compared to their...

spectroscopy

invited presentation

The limit of the nuclear stability, called neutron drip line, reflects structure of atomic nuclei with extremely proton-neutron asymmetry. It is known that the neutron drip line of oxygen isotope is 24O (Z=8, N=16), while that of fluorine is 31F (Z=9, N=22). This sudden change of the neutron drip line is called oxygen anomaly. Theoretical study [1] suggests that three-nucleon forces play an...

646. Nuclear collectivity studied with the newly refurbished Miniball spectrometer at HIE-ISOLDE

facilities/instruments

invited presentation

The Miniball spectrometer has been utilised for the study of collectivity in nuclei for two decades, exploiting post-accelerated radioactive ion beams at the ISOLDE facility. The workhorse technique has been Coulomb excitation, but few-nucleon and multi-nucleon transfer-reactions have also been exploited with the addition of ancillary devices such as the T-REX charged-particle...

639. OEDO-SHARAQ system: Its multifaceted performance and recent experimental achievements

Shin'ichiro Michimasa (Center for Nuclear Study, The University of Tokyo)

oral contribution

The OEDO-SHARAQ system at RIBF in RIKEN was primarily started to promote high-resolution nuclear spectroscopy with radioactive isotope (RI) beams. It was recently upgraded as the world's first beamline characterized by the energy-degrading of RI beams with a followed magnetic spectrometer for fragment analysis.

The high-resolution property of the system was fully demonstrated in the direct...
