Prospects of investigations on heavy ion beams at Dubna

Exceptional prospects and possibilities of heavy ion (HI) beams for basic and applied investigations are shown. The history of HI beams application for synthesis of superheavy elements with Z>=102 is briefly described; the results obtained are presented; prospects for further investigations are outlined. Another aspect of investigations is to study the mechanism of nuclear reactions with HI, as well as to study properties of super-heavy isotopes of lightest nuclei. To author's opinion, the rapid growth of quantity and quality of HI accelerators, and installations for carrying out investigations will promote, to a great extent, the development and application of these exceptional possibilities especially when solving problems, being inaccessible for another methods
