The present work is a continuation of our previous paper [J.-G. Deng, et al., Chin. Phys. C, 41:124109(2017)]. In the present work, the α decay half-life of the unknown nucleus296 Og is predicted within the two-potential approach and the hindrance factors of all 20 even-even nuclei in the same region as296 Og, i.e. proton number 82Z 126 and neutron number 152N 184, from250 Cm to294 Og, are extracted. The prediction is 1.09 ms within a factor of 5.12. In addition, based on the latest experimental data, a new set of parameters of α decay hindrance factors for the even-even nuclei in this region, considering the shell effect and proton-neutron interaction,are obtained. 相似文献

Based on the liquid-drop model and using the first derivative of the normalized Gaussian function to consider the shell correction, a simple α-decay energy formula is proposed for heavy and superheavy nuclei. The values of corresponding adjustable parameters are obtained by fittingα-decay energies of 209 nuclei ranging from Z = 90 to Z = 118 with N ≥ 140. The calculated results are in good agreement with the experimental data. The average and standard deviations between the experimental data and... 相似文献
