Alpha-decay chains observed in the element-115 production reactions of $$^{48}$$Ca + $$^{243}$$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-$$alpha$$-($$alpha$$)-fission type, fourteen of which were observed, and some of which were interpreted as the 2-neutron evaporation products $$^{289}$$Mc, have been reassigned. It is plausible that most of them were assigned to the 3-neutron evaporation products $$^{288}$$Mc whose decay chain would on the way have branches of EC decays followed by fission.

Thirty correlated $$alpha$$-decay chains of element 115 were observed, which were consistent with previous observations interpreted as the decay chain of $$^{288}$$115. GEANT4 Monte-Carlo simulations were performed to reproduce high-resolution $$alpha$$-photon coincidence results, which allows one to propose Q$$_{alpha}$$ values and excitation schemes of the superheavy nuclei with unprecedented precision.

A focal-plane Si detector setup applied to the spectroscopy of the element 115 $$alpha$$-decay chains was reported. Results of the digital signal analysis for preamplifier signals and of the event-by-event $$alpha$$-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 $$alpha$$ particles detected by two Si detectors at the bottom and a side differs event-by-event, because each $$alpha$$ particle passed through two dead layers with a certain tilted angle. By correcting for the energy loss of each $$alpha$$ event using the angle of the $$alpha$$-particle emission extracted from the detected positions, we succeeded in improving the $$alpha$$ energy resolution significantly.

Produced in the reaction of $$^{48}$$Ca beam with an $$^{243}$$Am target, thirty correlated $$alpha$$-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 $$alpha$$-photon coincidence measurement was performed, and $$gamma$$ rays as well as X-ray candidates were observed in this decay chain. The $$gamma$$-ray observation in the heaviest region of superheavy nuclei brings a big progress in the superheavy nuclear structure studies.
