本文研究了Z = 102-122的超重核与~（22）Ne、~（26）Mg、~（48）Ca、~（58）Fe和~（86）Kr等离子在库仑位垒附近和以下的聚变-裂变过程。实验是在弗莱罗夫核反应实验室的U-400加速器上进行的，使用了裂变碎片飞行时间谱仪CORSET和中子多探测器DEMON。作为实验的结果，研究了裂变碎片的质量和能量分布、裂变和准裂变截面、中子和伽马量子的多重性及其对复合超重系统形成和衰变机制的依赖性。
The process of fusion-fission of superheavy nuclei with Z = 102-122 formed in the reactions with22Ne,26Mg,48Ca,58Fe and86Kr ions at energies near and below the Coulomb barrier has been studied. The experiments were carried out at the U-400 accelerator of the Flerov Laboratory of Nuclear Reactions (JINR) using a time-of-flight spectrometer of fission fragments CORSET and a neutron multi-detector DEMON. As a result of the experiments, mass and energy distributions of fission fragments, fission and quasi-fission cross sections, multiplicities of neutrons and gamma-quanta and their dependence on the mechanism of formation and decay of compound superheavy systems have been studied.
