Ground state properties of Rn isotopes within the relativistic mean field theory
相对论平均场理论对Rn同位素链原子核基态性质的研究

The ground state properties of Rn isotopes are studied within the framework of relativistic mean field theory. The pairing correlation is treated by the BCS method. The calculation results are in good agreement with the experimental data. The quadrupole deformations can be founded mainly in the regions with neutron number far from magic number (N=110-124) and (N=129-142). In the regions where the neutron number is larger than the magic number(N=127-142), the hexadecapole deformations are also significant. The isotope shift for Rn isotope is also studied and a drastic change in the slope of the curve is found near the magic neutron nuclei.
