Times Cited Count：53 Percentile：95.13(Physics, Nuclear)Alpha-decay chains observed in the element-115 production reactions of Ca + Am were investigated using a new data set consisting of our recently reported data obtained at GSI and previously reported ones at Dubna and LBNL. Short decay chains of recoil--()-fission type, fourteen of which were observed, and some of which were interpreted as the 2-neutron evaporation products 
Mc, have been reassigned. It is plausible that most of them were assigned to the 3-neutron evaporation products 
Mc whose decay chain would on the way have branches of EC decays followed by fission.

Times Cited Count：7 Percentile：48.07(Chemistry, Analytical)Thirty correlated -decay chains of element 115 were observed, which were consistent with previous observations interpreted as the decay chain of 115. GEANT4 Monte-Carlo simulations were performed to reproduce high-resolution -photon coincidence results, which allows one to propose Q
values and excitation schemes of the superheavy nuclei with unprecedented precision.

Times Cited Count：8 Percentile：87.65(Physics, Nuclear)A focal-plane Si detector setup applied to the spectroscopy of the element 115 -decay chains was reported. Results of the digital signal analysis for preamplifier signals and of the event-by-event -energy loss correction analysis were presented. The detectors consist of five double-sided Si strip detectors (DSSSD) arranged as a box, and signals from one side of the detector at the bottom of the box were digitally processed. Energy losses of particles detected by two Si detectors at the bottom and a side differs event-by-event, because each particle passed through two dead layers with a certain tilted angle. By correcting for the energy loss of each event using the angle of the -particle emission extracted from the detected positions, we succeeded in improving the energy resolution significantly.

Observed decay chains are consistent with a previously reported decay chain, which confirms the identification of the element 115. In addition, an -photon coincidence measurement was performed, and 
rays as well as X-ray candidates were observed in this decay chain. The -ray observation in the heaviest region of superheavy nuclei brings a big progress in the superheavy nuclear structure studies.

Times Cited Count：11 Percentile：44.76(Materials Science, Multidisciplinary)Electron Paramagnetic Resonance (EPR) studies of the EI4 center in 4- and 6-Silicon Carbide (SiC) were carried out. The EI4 center was drastically enhanced in electron-irradiated high-purity semi-insulating materials by annealing at 700-750 
C. An additional large-splitting 
Si hf structure and 
C hf lines of the EI4 defect were observed. Comparing the data obtained from the hf interactions and the annealing behavior, and also from supercell calculations of different carbon-vacancy-related complexes, we propose a complex between a carbon vacancy-carbon antisite and a carbon vacancy at the third-neighbor site of the antisite in the neutral charge state, (V
-C
V)
, as a new defect model for the EI4 center.

Defects in high-purity semi-insulating 4H SiC irradiated with 2 MeV electrons at room temperature were studied using Electron paramagnetic resonance (EPR). The EPR signal named EI4 defect increased with annealing temperature up to 750 C. Additional large-splitting Si hyperfine (hf) structures and C hf lines by the interaction with one C nucleus were investigated. Based on the observed hf structures, the C
symmetry as well as the annealing behaviour, the EI4 defects is determined to be the complex between two carbon vacancies and a carbon antisite in the neutral charge state, VVC. The formation of the complex is interpreted in terms of the migration of the silicon vacancy and the formation of the carbon vacancy-carbon antisite pair next to a carbon vacancy.

Data from a wide variety of interesting discharges from many of the world's leading tokamak experiments are now made available in PR08, which also includes predictive simulations of an initial set of operating scenarios for ITER. In this paper we describe the discharges that have been included and the tools that are available to the reader who is interested in accessing and working with the data.
