Description
Summary:The maximum magic number of neutrons for existing nuclei can be 260, protons - 126. The maximum deformation of existing super-heavy nuclei corresponds to the number of protons is about 120, the number of neutrons is about 120, 155 and 222. The islands (or shallows) of stability can be formed not only around the 298Fl, but also around the 320120 and 342126. The islands are extended toward larger numbers of neutrons. An increase in the half-life should be observed for the 348126 and 386126. The half-life of 298Fl is ∼107...108 years. This is an understated estimate. The half-life of the longest-lived isotope of the 126th element with a mass number of 342 is ∼106...107 s (or 0.03...0.33 years).
