摘要
The alpha decay half-life of the unknown nucleus (297)Og is predicted within the two-potential approach, and alpha preformation probabilities of 64 odd-A nuclei in the region of proton numbers 82 < Z < 126 and neutron numbers 152 < N < 184, from Cf-251 to (295)Og, are extracted. In addition, based on the latest experimental data, a new set of parameters fora preformation probabilities considering the shell effect and proton-neutron interaction are obtained. The predicted a. 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.
