The existence of long lived superheavy nuclei (SHN) is controlled mainly by spontaneous fission and {alpha}-decay processes. According to microscopic nuclear theory, spherical shell effects at Z=114, 120, 126 and N=184 provide the extra stability to such SHN to have long enough lifetime to be observed. To investigate whether the so-called 'stability island' could really exist around the above Z, N values, the {alpha}-decay half-lives along with the spontaneous fission and {beta}-decay half…

Competition between α-decay and spontaneous fission for superheavy nuclei
The α-decay half-lives of recently synthesized superheavy nuclei (SHN) are investigated by employing a unified fission model (UFM) and Royer's analytical formula (2000 J. Phys. G: Nucl. Part. Phys.
Predictions for decay modes for superheavy nuclei Z=118–124
To study whether long-lived superheavy nuclei could really exist around $Z=120$ and $N=184$, the competition between $\ensuremath{\alpha}$ decay and spontaneous fission in the region
Possible α decay chains from isotopes of superheavy element 120
We investigate the α decay half-lives of even-Z superheavy nuclei up to Z = 120 by the modified two-potential approach. Based on the density-dependent cluster model, the α daughter potential is
Probable Heavy Particle Decays from 306–339128 Superheavy Nuclei
The heavy particle decays that are probable from the isotopes of Z = 128 superheavy nuclei within the range A = 306–339 have been analyzed within the Coulomb and proximity potential model (CPPM). The
Half-lives and fine structure for the α decay of deformed even-even nuclei
The α-decay properties of well-deformed even-even nuclei are systematically calculated within the multichannel cluster model (MCCM). Instead of working in the WKB framework, the quasibound solution
Experimental searches for rare alpha and beta decays
Abstract.The current status of the experimental searches for rare alpha and beta decays is reviewed. Several interesting observations of alpha and beta decays, previously unseen due to their large


Systematical law of spontaneous fission half-lives of heavy nuclei
Systematic calculations on spontaneous fission half-lives of heavy nuclei are carried out by Swiatecki's formula with new parameters and by its generalized form. A new formula with only four
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.
Valleys due to Pb and Sn on the potential energy surface of superheavy and lighter α-emitting nuclei
The strong shell effects of the magic nuclei 208Pb, 132Sn and 102Sn are the origin of valleys on the potential energy surfaces (PES) of the superheavy nucleus 294118 and of the alpha emitters 212Po
Spontaneous-fission half-lives of deformed superheavy nuclei.
Spontaneous-fission half-lives of the heaviest nuclei are analyzed in a multidimensional deformation space and are predicted for many unknown nuclei, sufficient to detect them if synthesized in a laboratory.
Nuclear physics: Island ahoy!
Spectroscopy of the nobelium isotope, 254No reveals three excited structures, two of them metastable, which will help to constrain nuclear models of the superheavy elements, and provides more data for the search for the next magic numbers.
Theoretical Estimates of Spontaneous-Fission Half-Lives for Superheavy Elements Based on the Modified-Oscillator Model
The stability problem for the superheavy elements has been reconsidered based on the use of the shape-dependent droplet model and the modified-oscillator potential. The effect of axial asymmetry on
