“…1, 2 and references given in [1][2][3]), as well as SF lifetimes of SHN (see, e.g., Fig. 5 in [11]) which are largely dependent on fission barriers of nuclei, are in reasonable agreement with experimental data. Therefore, the fundamental outcomes of the microscopic theory concerning the predictions of the "Island of stability" of SHN were validated by experimental evidence.…”

“…For heavier even-even nuclei, 288 Fl, 290 Lv, 292 Lv, and 294 118, SF was not detected due to the more considerable rise of stability with regard to SF compared to decay, with the neutron number approaching the magic number N = 184. On the other hand, the considerable drop of the evaporation cross sections observed for the reactions with neutron-deficient isotopes 239 Pu and 240 Pu (by a factors of about fifty and four, respectively, in comparison with that for the reaction with the heavier isotope 244 Pu [11]) indicates one is approaching the neutron-deficient border of stability of SHN.…”

“…Furthermore, the decay properties of 294 283 Cn and their descendants were determined in different laboratories with use of different techniques (separators DGFRS, SHIP, TASCA, BGS, GARIS, and chemistry setups) that is in accordance with demand of reproducibility for recognition of the discovery of new elements (see [1,3,5,10,11,[15][16][17][18], references therein, and proceedings of this Symposium).…”

Abstract. Discovery and investigation of the "Island of stability" of superheavy nuclei at the separator DGFRS in the 238 U-249 Cf+ 48 Ca reactions is reviewed. The results are compared with the data obtained in chemistry experiments and at the separators SHIP, BGS, TASCA, and GARIS. The synthesis of the heaviest nuclei, their decay properties, and methods of identification are discussed and compared with the criteria that must be satisfied for claiming the discovery of a new chemical element. The role of shell effects in the stability of superheavy nuclei is demonstrated by comparison of the experimental results with empirical systematics and theoretical data.

“…Combined data from both cold and hot fusion reactions (see Sect. 3) reaching from Z = 106 to Z = 118 show clear evidence of a shell at N = 162 and also show a strong decrease of -particle energy when N increases beyond 165, an indication of approaching a closed shell, possibly at N = 184 [18]. These observations go hand in hand with the increasing half-lives as N = 184 is approached.…”

“…One of them is: "what can be the largest possible atomic number Z of an atomic nucleus?". The current answer was gained thanks to the tremendous advance in experimental studies achieved in recent years [1][2][3][4][5] via fusion-evaporation reactions, once the element Z=118 has been synthesized [6]. Question if we can go still further waits for an answer as attempts to go beyond Z=118 hit two obstacles: (i) a difficulty or impossibility of making targets from Es and heavier actinides, (ii) reactions with heavier projectiles like: 50 Ti, 54 Cr, 58 Fe, and 64 Ni, did not produce any ERs up to now.…”

Fusion-fission probabilities, cross sections, and structure notes of superheavy nuclei

et al. 2016

Abstract. Fusion -fission probabilities in the synthesis of heaviest elements are discussed in the context of the latest experimental reports. Cross sections for superheavy nuclei are evaluated using the "Fusion by Diffusion" (FBD) model. Predictive power of this approach is shown for experimentally known Lv and Og isotopes and predictions given for Z = 119, 120. Ground state and saddle point properties as masses, shell corrections, pairing energies, and deformations necessary for cross-section estimations are calculated systematically within the multidimensional microscopicmacroscopic method based on the deformed Woods-Saxon single-particle potential. In the frame of the FBD approach predictions for production of elements heavier than Z = 118 are not too optimistic. For this reason, and because of high instability of superheavy nuclei, we comment on some structure effects, connected with the K-isomerism phenomenon which could lead to a significant increase in the stability of these systems.
