Abstract：
With pairing correlations and microscopic center-of-mass correction considered, new parameter sets for the Lagrangian density in the relativistic mean field (RMF) theory, NLLN with nonlinear σ- and ω-meson self-coupling and DDLN with the density-dependent meson-nucleon coupling are proposed for light nuclei. They are able to provide an excellent description for the properties of the Z≤8 nuclei in and far from the valley of β stability. The neutron drip line nucleus ²⁶O for Oxygen isotopes is obtained in new parameter sets. In addition new magic number N=16 in ²⁴O can be well explained in new frame.
