被引用回数：7 パーセンタイル：76.16(Physics, Nuclear)At RIKEN RIBF facility, the beta decay of 
Sb and 
Sb were studied and several new excited states were assigned to the level schemes of Te and Te. The structure of these Te isotopes deduced from the level scheme is compared with state-of-the-art shell-model calculations using different effective interactions. The comparison with calculations permits to determine the spectroscopic factors and deformation of these isotopes close to doubly magic 
Sn.

被引用回数：4 パーセンタイル：33.25(Instruments & Instrumentation)We have developed a time-of-flight (ToF) array consisting of 24 plastic scintillators for triggering and timing measurements in a series of planned experiments to study double-strangeness hadronic and nuclear systems at the K1.8 beamline of J-PARC. Each ToF scintillator is 180 cm long with a cross-section of 8
3 cm
and is read out by H1949-50 photomultiplier tubes at both ends. The timing and attenuation properties of the scintillators are measured using cosmic-ray muons and 
rays from 
. The cosmic-ray muon events are triggered by three pairs of 120-cm-long plastic scintillators, sandwiching the ToF array. The intrinsic time resolutions of the scintillators are estimated to be in the range 60-100 ps, which is adequate for reliable separation between 
and 
at 1.2 GeV/
. The attenuation length is measured to be approximately 210 cm, which is half that for a bulk scintillator.

被引用回数：24 パーセンタイル：76.91(Physics, Multidisciplinary)A new isomer with a half-life of 23.0(8) ms has been identified in Pd at 2406 keV excitation. The proposed spin and parity configuration is 10
, with maximally aligned configuration of two 
neutron hole. -decay from the long-lived isomer was also observed to populated excited states at high spins in Ag. The small energy difference between the 10 and 7
isomers in Pd was interpreted in the frame of the monopole shift of the 1 neutron orbit. The effects of the monopole interaction on the evolution of single-neutron energies below Sn are discussed in terms of central and tensor forces.
