We study the impact of the nuclear symmetry energy and its density dependence on the α-decay process. Within the frame work of the performed cluster model and the energy density formalism, we use different parameterizations of the Skyrme energy density functionals that yield different equations of state EOSs. Each EOS is characterized by a particular symmetryenergy coefficient (a sym ) and a corresponding density-slope parameters L. The stepwise trends of the neutron (proton) skin thickness of the involved nuclei with both a sym and L do not clarify the obtained oscillating behaviors of the αdecay half-life T α with them. We find that the change of the skin thickness after α-decay satisfactory explains these behaviors. The presented results provide constrains on a sym centered around an optimum value a sym = 32 MeV, and on L between 41 and 57 MeV. These values of a sym and L, which indicate larger reduction of the proton-skin thickness and less increase in the neutron-skin thickness after an α-decay, yield minimum calculated half-life with the same extracted value of the α-preformation factor inside the parent nucleus.PACS number(s): 23.60.+e, 21.60.Jz, 21.65.Mn, 21.10.Gv, 21.65.Ef
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
