摘要

The α decay half-life of the unknown nucleus 297Og 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 251Cf to 295Og,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 297Og is 0.16 ms within a factor of 4.97.The predicted spin and parity of the ground states for 269Sg,285Fl and 293Lv are 3/2+,3/2+ and 5/2+,respectively.
