Calculation of α half-lives for Z ≥ 94 nuclei by proximity potential with a new universal function

The half-lives of even-even nuclei with proton number Z≥94 are calculated by proximity potential with a new universal function, especially for superheavy nuclei. The calculation results are compared to the experimental data. It is shown that from the presently obtained universal function, the calculated half-lives of α decay can basically keep agreement with the experimental data for most of even-even nuclei. Those of superheavy nuclei are also calculated and discussed.
