摘要:
The α decay half-life of the unknown nucleus ~(297)Og is predicted within the two-potential approach, and α preformation probabilities of 64 odd-A nuclei in the region of proton numbers 82<Z< 126 and neutron numbers 152<N<184, from ~(251)Cf to ~(295)Og, are extracted. In addition, based on the latest experimental data, a new set of parameters for α preformation probabilities considering the shell effect and proton-neutron interaction are obtained. The predicted α decay half-life of ~(297)Og is 0.16 ms within a factor of 4.97. The predicted spin and parity of the ground states for ~(269)Sg, ~(285)Fl and ~(293)Lv are 3/2~+,3/2~+ and 5/2~+,respectively.
