摘要：

An overview of present experimental investigation of superheavy elements is given. Using cold fusion reactions which are based on lead and bismuth targets, relatively neutron deficient isotopes of the elements from 107 to 112 were synthesized at GSI in Darmstadt, Germany, a neutron deficient isotope of element 113 at RIKEN in Wako, Japan. In hot fusion reactions of Ca-48 projectiles with actinide targets more neutron rich isotopes of element 112 and new elements up to 118 were produced at FLNR in Dubna, Russia. Recently, part of these data which represent the first identification of nuclei located on the predicted island of SHEs, was confirmed in independent experiments. The measured data combined with theoretical results were used for estimating cross-sections for production of element 120 isotopes. Also evaluated were their decay properties. An experiment for searching of isotopes of element 120 is planned at the GSI SHIP.
