Abstract：
The αdecay half-life of the unknown nucleus ²⁹⁷Og is predicted within the two-potential approach, and αpreformation 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 αpreformation probabilities considering the shell effect and proton-neutron interaction are obtained. The predicted αdecay 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.
