Times Cited Count：156 Percentile：99.31(Physics, Multidisciplinary)This paper introduces a new approach to measure the muon magnetic moment anomaly 
and the muon electric dipole moment (EDM) 
at the J-PARC muon facility. The goal of our experiment is to measure 
and using an independent method with a factor of 10 lower muon momentum, and a factor of 20 smaller diameter storage-ring solenoid compared with previous and ongoing muon g-2 experiments with unprecedented quality of the storage magnetic field. Additional significant differences from the present experimental method include a factor of 1000 smaller transverse emittance of the muon beam (reaccelerated thermal muon beam), its efficient vertical injection into the solenoid, and tracking each decay positron from muon decay to obtain its momentum vector. The precision goal for is a statistical uncertainty of 450 parts per billion (ppb), similar to the present experimental uncertainty, and a systematic uncertainty less than 70 ppb. The goal for EDM is a sensitivity of

Times Cited Count：12 Percentile：46.43(Physics, Condensed Matter)The muon science facility (MUSE) is one of the experimental areas of the J-PARC. The MUSE facility is located in the Materials and Life Science Facility (MLF), which is a building integrated to include both neutron and muon science programs. Construction of the MLF building was started at the beginning of 2004, and was recently completed at the end of the 2006 fiscal year. We have been working on the installation of the beamline components, expecting the first muon beam in the autumn of 2008.

Times Cited Count：20 Percentile：73.35(Physics, Nuclear)High-spin states in Os have been studied using the 170Er(18O,5n) reaction at a beam energy of 85 MeV. Nine rotational bands based on 1-, 3-, 5- and 7-quasiparticle excitations have been observed. Nilsson configurations are assigned for the newly observed bands using g-factors deduced from M1/E2 branching ratios within the bands. In addition, two isomers with K=(43/2+) and (43/2-) have been identified. The K=(43/2+) isomer decays directly to the K=9/2+ ground state band with a large difference in the 
quantum number, 
17. The decay rates are disccused in terms of a tunneling model where high- (isomeric) and low- states interact via fluctuations towards triaxial nuclear shapes.

A high-resolution beam imaging system was newly developed for pulsed muon beams in J-PARC MUSE using a plastic scintillator, a gated image intensifier, and a cooled CCD camera. The system was optimized for observation of 4 MeV muon beams and designed so as to be used with an existing muSR spectrometer in the D1 area, J-PARC MUSE. High-resolution beam profiles were obtained for a surface muon beam after exposure to the beam for several tens of seconds. A contribution from decay positrons was significantly suppressed by gating of the image ntensifier. Details of test experiments (negative muon beam profiles in the D2 area, 3D beam imaging, noise reduction, etc.) were presented.
