Times Cited Count：50 Percentile：91.08(Physics, Multidisciplinary)Fission-fragment mass distributions were measured for 
U, 
Np and 
Pu populated in the excitation-energy range from 10 to 60 MeV by multi-nucleon transfer channels in the reaction 
O + 
U at the JAEA tandem facility. Among them, the data for 
U and 
Np were observed for the first time. It was found that the mass distributions for all the studied nuclides maintain a double-humped shape up to the highest measured energy in contrast to expectations of predominantly symmetric fission due to the washing out of nuclear shell effects. From a comparison with the dynamical calculation based on the fluctuation-dissipation model, this behavior of the mass distributions was unambiguously attributed to the effect of multi-chance fission.

Times Cited Count：3 Percentile：24.98(Instruments & Instrumentation)For the J-PARC E40 experiment which aims to measure differential cross-sections of Sp scatterings, a system to detect scattered proton from Sp scatterings is under development. The detection system consists of scintillation fibers with a MPPC readout. A prototype and a readout electronics for MPPC have already been developed. The prototype consisting of a scintillation fiber tracker and a BGO calorimeter was tested with a proton beam of 80 MeV. Energy resolutions of the tracker of 22.0% (s) and the calorimeter of 1.0% (s) were obtained for 1 MeV and 70 MeV energy deposit, respectively. The prototype readout electronics has an ASIC for multichannel operation, EASIROC, and a Silicon TCP (SiTCP) interface to communicate with a DAQ system. Its data transfer rate measured was 14 kHz. Required performances for the prototype system have been achieved except for the energy resolution of the prototype fiber tracker.
