摘要：

The center of the predicted island of stability of superheavy nuclei (SHN) has not yet been observed experimentally. Many theories are being developed to understand the synthesizing mechanism of superheavy nuclei. However, all of them have to use some basic nuclear data. Three data tables, FRDM1995 [P. Moller et al., At. Data Nucl. Data Tables 59, 185 (1995)], KTUY2005 [H. Koura et al., Prog. Theor. Phys. 113, 305 (2005)], and WS2010 [NingWang et al., Phys. Rev. C 82, 044304 (2010)], are used to investigate the SHN production. Based on the dinuclear system concept, the evaporation residue cross sections of SHN for Z=112-118 are calculated for the Ca-48-induced hot fusion reactions. It turns out that unlike the predictions made with the KTUY2005 and WS2010 data, the magic numbers Z=114 and N=184 predicted with the FRDM1995 data do not contradict the experimental data obtained so far.
