摘要
This paper presents a brief review of the existing approaches to the creation of superheavy nuclei in collisions of heavy nuclei to overcome the Coulomb barrier or through the pion condensation in a nucleus volume. A principally new approach to the creation of superheavy nuclei based on the stimulation of a self-organizing collapse of electron-nuclear systems is analyzed. For a neutral atom compressed by external forces, a threshold electron density is shown to exist. If such a density is reached, a self-organizing process of "electron downfall to the nucleus" starts. This process is exoenergic and leads to the formation of a supercompressed electron-nuclear cluster. The higher the charge of a nucleus, the lower the threshold of the external compression. It is shown that the maximum binding energy shifts during such a self-organizing collapse of the electron-nuclear system from A(opt) approximate to 60 (for uncompressed substance) to the area of high mass numbers A(opt) greater than or equal to 200... 2000 and could render the synthesis of superheavy nuclei to be energy-efficient. The synthesis proceeds through the absorption of other nuclei by the collapsed nucleus. It is theoretically proved that the synthesis efficiency is ensured by both the width reduction and increased transparency of the Coulomb barrier in the extremely compressed electron-nuclear system. The release of binding energy through the absorption of nuclei by the electron-nuclear collapsed clusters may result in the simultaneous emission of lighter nuclei. It is assumed that just such a mechanism of synthesis explains the creation of superheavy and other anomalous nuclei observed in the experiments carried out at the Electrodynamics Laboratory "Proton-21."
