Structure and Decay Modes of Superheavy Nuclei

Abstract

One calculated the \(\alpha \)-decay (Budaca and Silisteanu 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]).
