摘要
Simple formulas for alpha-half-lives derived from the systematics of measured and calculated alpha-half-lives [Rom. J. Phys. 62, 303 (2017)] of superheavy nuclei, are used to predict the alpha-half lives of the nuclei around the expected double magic nucleus 304120. Present alpha-half-life estimates for nuclei near closed shells are compared to available data and results of other methods. We get almost identical alpha-half-lives for decays of Te-104, Po-212 and (308)122 leading to known Sn-100, Pb-208 or (304)120 doubly magic nuclei. The competition between a decay and fission at the closed shells is discussed.
