Times Cited Count:8 Percentile:52.11(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:89.92(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.

Times Cited Count:22 Percentile:73.51(Physics, Multidisciplinary)Produced in the reaction of Ca beam with an
Am target, thirty correlated
-decay chains were observed. 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.
