Structure and Decay Modes of Superheavy Nuclei

Abstract

One calculated the $\alpha$-decay (Budaca and Silişteanu Phys Rev C 88:044618, 2013 [1]; Silisteanu and Budaca At Data Nucl Data 98:1096, 2012 [2]) and spontaneous fission (SF) (Karpov et al Int J Mod Phys E 21:1250013, 2012 [3]) half-lives of superheavy nuclei with formulas derived from the systematics of experimental data and theoretical results. The parameters of the resulted formula are obtained from the fit of half-lives (Silisteanu and Anghel Rom J Phys 60:444–451, 2015 [4]; Silisteanu and Anghel Rom J Phys 59:724–732, 2014 [5]) in respect with the reaction energies $Q_{\alpha }$, the height of the SF barrier $B_{f}$ and the fissionability $Z^{2}/A$. The calculated partial and total half-lives $T_{\alpha }$, $T_{SF }$, $T_{t}$ are compared with the data (http://www.nndc.bnl.gov/chart [6]).
