| 内容記述 | The study of 254Es via Coulomb excitation gamma-ray spectroscopy has been performed at the JAEA-Tokai Tandem Laboratory using a 58Ni beam with an energy of 250 MeV. The detector system includes: 4 single-crystal HPGe detectors, 4 LaBr3(Ce) scintillators and 4 Clover type HPGe detectors and 2 CD silicon detectors placed backward and forward to the target for detecting scattered particle. A “safe” Coulomb excitation of 254Es was achieved for the first time to study its excited states. The 254Es gamma-ray spectrum was investigated by gating on the scattered 58Ni particle measured by the CD Si detectors. The gamma spectrum created after gain matching and Doppler shift correction was analyzed. From the gamma spectrum, several new transitions of 254Es were observed and they indicated the rotational band structure. The extracted data could help to extend the 254Es level scheme and determine its quadrupole deformation. | |||||
