Mapping of a New Deformation Region around $^{62}$Ti

We perform the first direct mass measurements of neutron-rich titanium isotopes around neutron number $40$ at the RIKEN Radioactive Isotope Beam Factory by using the time-of-flight magnetic-rigidity technique. The atomic mass excesses of measured nuclei suggest emergence of the Jahn-Teller stabilization around $^{62}$Ti.

OEDO, the energy-degrading beamline at RI Beam Factory

We constructed the Optimized Energy Degrading Optics (OEDO) beamline is an upgrade of the High-resolution beamline at the RI Beam Factory at RIKEN.

Magic Nature of Neutrons in $^{54}$Ca: First Mass Measurements of $^{55-57}$Ca

We perform the first direct mass measurements of neutron-rich calcium isotopes beyond neutron number $34$ at the RIKEN Radioactive Isotope Beam Factory by using the time-of-flight magnetic-rigidity technique. The atomic mass excesses of $^{55–57}$Ca are determined for the first time.
