AbstractA recent proposed method for alpha-decay energies (Q(alpha)) [J. M. Dong, W. Zuo, and W. Scheid, Phys. Rev. Lett. 107, 012501 (2011)] can reproduce experimental data of superheavy nuclei (SHN) 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, we have further extended this hybrid method, i.e., to predict Q(alpha) of the as-yet-unobserved SHN with the help of known nuclei. It is found that the systematic deviation seen in the previous study 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.
