Mass predictions of superheavy nuclei from the systematics of
$α$-Decay Energies

Z. Li, B. Sun, C. H. Shen, W. Zuo
A recent proposed method for $\alpha$-decay energies [J.M. Dong, W. Zuo, and W. Scheid, Phys. Rev. Lett. \textbf{107}, 012501 (2011)] can reproduce experimental data with an $rms$-value of less than 100 keV. However, a sinusoid-like periodic deviation from experiments, which limits the accuracy in predictions, is observed when using different reference nuclei. In this paper, it is found that the systematic deviation is rooted in the nuclear mass model employed. By further analyzing the source of errors, different nuclear mass models are evaluated based on the same procedure.
