Description
During last decade the heaviest elements with Z=113-118 were discovered in Dubna in fusion reactions of 48Ca beam with appropriate actinide targets. The 48Ca program of synthesis of new elements is over as no heavier target than Californium is available. However 48Ca-based fusion reactions may be still used, in particular, for exploring new lands on the nuclear map. The perspectives of discovering new elements heavier than Z=118 as well as of synthesis of new isotopes of super-heavy (SH) nuclei are discussed in this talk. In particular, we found for the first time a narrow pathway leading to the centre of the island of stability of SH nuclei owing to possible beta+-decay of SH nuclei. The conclusions are based on the recent calculations of decay properties of heavy and SH nuclei with respect to alpha-decay, beta-decay and spontaneous fission.
