α decay properties of 296Og within the two-potential approach

  • 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 nucleus 296Og is predicted within the two-potential approach and the hindrance factors of all 20 even-even nuclei in the same region as 296Og, i.e. proton number 82 < Z < 126 and neutron number 152 < N < 184, from 250Cm to 294Og, 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.
