Nuclear Structure Studies in the Vicinity of the Doubly Closed Shell Nuclei exp 132 SN and exp 208 PB by Means of beta and alpha Decay

摘要

Experimental data of neutron-rich even tin, antimony and tellurium nuclei studied in beta decay are presented. Some of these nuclei are differing from the doubly closed shell nucleus exp 132 Sn in only a few nucleons. The alpha decay of astatine and polonium nuclei in the vicinity of the doubly closed shell nucleus exp 208 Pb has also been studied. The short-lived beta and alpha activities have been analysed using an isotope separator on-line technique. The experimental results have been compared to calculations performed within the nuclear shell model. (Atomindex citation 12:640441)
