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
