Properties of the hypothetical spherical superheavy nuclei
Abstract
Theoretical results on the groundstate properties of the hypothetical spherical superheavy atomic nuclei are presented and discussed. Eveneven isotopes of elements Z=104120 are considered. Certain conclusions are also drawn for oddA and oddodd superheavy nuclei. Results obtained earlier for eveneven deformed superheavy nuclei with Z=104114 are given for completeness. Equilibrium deformation, nuclear mass, αdecay energy, αdecay halflife, dynamical fission barrier, as well as spontaneousfission halflife are considered. βstability of superheavy nuclei is also discussed. The calculations are based on the macroscopicmicroscopic model. A multidimensional deformation space describing axially symmetric nuclear shapes is used in the analysis of masses and decay properties of superheavy nuclei. We determined the boundaries of the region of superheavy nuclei which are expected to live long enough to be detected after the synthesis in a presentday experimental setup.
