A region of long-lived superheavy elements with proton and neutron numbers near Z=114, Z=120, N=184 – the so-called “Island of Stability” (IoS) is predicted to be the next “promised land”. Currently, access to the IoS is limited by the very low cross sections that affect present experimental techniques. Single-particle orbitals neighboring the deformed shell gaps in the region near Z=100 and N=152 are predicted to be linked to the spherical shells in the IoS. This link provides indirect information on the shell structure of nuclei in the IoS. 254Es (Einsteinium-254, Z=99, N=155) is an isotope in the region of deformed shell gaps and currently the heaviest target available for Coulomb excitation experiments.\nA 254Es Coulomb excitation experiment was performed at the JAEA-Tokai Tandem accelerator using 58Ni beam with an energy of 250 MeV. The very rare 254Es was produced at the High-Flux Isotope Reactor at ORNL, USA, and the target was produced using less than a microgram of material. The scattered beam particles were detected by two segmented CD-silicon detectors placed backward and forward from the target in coincidence with γ rays detected by 4 LaBr3(Ce) scintillators, 4 single-crystal Ge detectors and 4 Clover-type Ge detectors. Safe Coulomb excitation of 254Es was achieved for the first time to study its excited states. The particle-gamma coincidence spectrum created after Doppler-shift correction was analyzed. From the gamma spectrum, several new transitions of 254Es were observed indicating a rotational band structure. The extracted data will permit extending the 254Es level scheme and to determine its quadrupole deformation.\n","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期,
