“…This would 5 predict a valley of fission instability in this particular region of superheavies. On the other hand there is experimental evidence [53] The calculation of main ingredients of the theory, namely the PES and the collective mass parameter were described elsewhere [28,25]. We map the deformation landscape by adding a quadrupole constraint stretching the system successively to scission.…”

This is a short review of methods and results of calculations of fission barriers and fission halflives of even-even superheavy nuclei. An approvable agreement of the following approaches is shown and discussed: The macroscopic-microscopic approach based on the stratagem of the shell correction to the liquid drop model and a vantage point of microscopic energy density functionals of Skyrme and Gogny type selfconsistently calculated within Hartree-Fock-Bogoliubov method. Mass parameters are calculated in the Hartree-Fock-Bogoliubov cranking approximation. A short part of the paper is devoted to the nuclear fission dynamics. We also discuss the predictive power of Skyrme functionals applied to key properties of the fission path of 266 Hs. It applies the standard techniques of error estimates in the framework of a χ 2 analysis.

Half-lives of superheavy elements (SH) with 108 ≤ Z ≤ 126 and 148 ≤ N ≤ 188 are calculated from decay energies, fission barriers and the mass parameters that have been obtained in a uniform microscopic way within a selfconsistent Hartree-Fock-Bogoliubov (HFB) method, SkM * force in the particle-hole channel and the density dependent delta interaction in the particle-particle channel. We consider α-decay, spontaneous fission (SF) and β processes (β ± and electron capture). The results indicate that the longest total half-lives are of the order of seconds for a set of nuclei in the vicinity of Z = 112, N = 182.

“…Studying nuclear structure of superheavy elements (SHE) (Z > 100) is an important area of research taking nuclear physics to unexplored territory and potentially leading to hypothetical island of stability [1][2][3][4][5][6]. The sources of experimental information are very limited since the SHE are not found in nature but produced at accelerators at very low production rate.…”

We calculate field isotope shifts for nobelium atoms using nuclear charge distributions which come from different nuclear models. We demonstrate that comparing calculated isotope shifts with experiment can serve as a testing ground for nuclear theories. It also provides a way of extracting parameters of nuclear charge distribution beyond nuclear RMS radius, e.g. parameter of quadrupole deformation β. We argue that previous interpretation of the isotope measurements in terms of δ r 2 between 252,254 No isotopes should be amended when nuclear deformation is taken into account. We calculate isotope shifts for other known isotopes and for hypothetically metastable isotope 286 No for which the predictions of nuclear models differ substantially.
