Abstract

Decay properties of superheavy nuclei are required for exploring the nuclei from the upper part of the nuclear map. The stability of nuclei with \(Z\le 132\) is studied with respect to \(\alpha \)-decay, \(\beta \)-decay and spontaneous fission. Performed calculations allow us to conclude that at existing experimental facilities the synthesis and detection of nuclei with \(Z>120\) produced in fusion reactions may be difficult due to their short half-lives (shorter than 1 \(\upmu \)s). We found for the first time the region of \(\beta ^{+}\)-decaying superheavy nuclei with \(111\le Z\le 115\) located to the “right” (more neutron-rich) to those synthesized recently in Dubna in \(\mathrm{^{48}}\mathrm{Ca}\)-induced fusion reactions. This fact may significantly complicate their experimental identification. However it gives a chance to synthesize in fusion reactions the most stable superheavy nuclei located at the center of the island of stability. Our calculations yield that the \(\beta \)-stable isotopes \(^{291}\)Cn and \(^{293}\)Cn with a half-life of about 100 years are the longest-living superheavy nuclei located at the island of stability.
