| Abstract: | A form of densities suitable for applications of extended Thomas-Fermi(ETF)method is proposed.With SkM* force parameters,ground state properties of some Spherical nuclei are calculated.The results,in a general way,are better than those with ordinarily parametrized densities. Further application of the expectation value method(EVM)can also reproduce Hatree-Fock(H-F)results. |
