Decay properties of superheavy nuclei are required for exploring the nuclei from the upper part of the nuclear map. The stability of nuclei with \(Z\le 132\) is studied with respect to \(\alpha \)-decay, \(\beta \)-decay and spontaneous fission. Performed calculations allow us to conclude that at existing experimental facilities the synthesis and detection of nuclei with \(Z>120\) produced in fusion reactions may be difficult due to their short half-lives (shorter than 1 \(\upmu \)s). We found…

DECAY PROPERTIES AND STABILITY OF HEAVIEST ELEMENTS

Decay properties and stability of heaviest nuclei with Z≤132 are studied within the macro-microscopical approach for nuclear ground state masses and phenomenological relations for the half-lives with

Properties of the hypothetical spherical superheavy nuclei

Theoretical results on the ground-state properties of the hypothetical spherical superheavy atomic nuclei are presented and discussed. Even-even isotopes of elements Z=104{minus}120 are considered.

Superheavy nuclei and quasi-atoms produced in collisions of transuranium ions

Low energy collisions of very heavy nuclei ($^{238}\mathrm{U}+^{238}\mathrm{U}$, $^{232}\mathrm{Th}+^{250}\mathrm{Cf}$, and $^{238}\mathrm{U}+^{248}\mathrm{Cm}$) have been studied within the

Synthesis of superheavy nuclei: A search for new production reactions

Nuclear reactions leading to the formation of new superheavy (SH) elements and isotopes are discussed in the paper. 'Cold' and 'hot' synthesis, fusion of fission fragments, transfer reactions, and

Production of heavy and superheavy neutron-rich nuclei in transfer reactions

The problem of production and study of heavy neutron-rich nuclei has been intensively discussed during recent years. Many reasons arouse a great interest in this problem. The present limits of the

On the stability of superheavy nuclei against fission

We use the methods, which we developed in a previous paper, for the calculation of potential energy surfaces and lifetimes for superheavy nuclei. Two regions of relative stability against spontaneous

Possibilities for synthesis of new isotopes of superheavy elements in fusion reactions

Background. In the “cold” fusion reactions based on the use of lead and bismuth targets, the proton-rich isotopes of superheavy (SH) elements up to Z = 113 have been produced. More neutron-rich
