Properties of Z=117 Isotopic Chain and its α decay time

【摘要】：正The properties of Z=117 isotopic chain have been studied within the framework of the axially deformed relativistic mean field theory(RMFT) in the blocked BCS approximation.The ground-state properties, such as binging energies,deformations as well as the possibleαdecay energies and lifetimes are calculated with parameter set of NL-Z2 and compared with results from the finite range droplet model.The analysis by RMFT shows that the isotopes in the range of mass number A = 291～300 exhibit higher stability,which suggests that they may be the promising nuclei to be hopefully synthesized in the lab among the nuclei Z=117.
