英文摘要: Based on the systematic investigation of the data available for nuclei with A greater than or equal to 40, a Z(1/3)-dependence for the nuclear charge radii is shown to be superior to the generally accepted A(1/3) law. A delicate scattering of data around R-c/Z(1/3) is inferred as owing to the isospin effect and a linear dependence of R-c/Z(1/3) on N/1Z (or (N-Z)/2) is found. This inference is well supported by the microscopic Relativistic Continuum Hartree-Bogoliubuv (RCHB) calculation conducted for the proton magic Ca, Ni, Zr, Sn and Pb isotopes including the exotic nuclei close to the neutron drip line. With the linear isospin dependence provided by the data and RCIIB theory, a new isospin-dependent Z(1/3) formula for the nuclear charge radii is proposed.
