α-Cluster structure above double-shell closures and α-decay of 104Te

摘要

An analysis of theα+coreproperties of104Te along with a global discussion on theα-cluster structure above the double-shell closures is presented from the viewpoint of the local potential model. Theα+coreinteraction is described by a nuclear potential of (1 + Gaussian)×(W.S. + W.S.3) shape with two free parameters, which has been successfully tested in nuclei of different mass regions. The model producesQαvalues andα-decay half-lives for104Te in agreement with the 2018 experimental data of Auranen et al. in the energy range5.13?MeV
