Effective nuclear charge (Zeff) is the “positive charge” felt by an electron. 参考答案:对 点击查看答案&解析
Abstract The valence force constants of planar and pyramidal XY3 molecules are calculated on the basis of the effective nuclear charge model previously developed. The calculated results are compared with the experimental force constants which are determined by the normal coordinate analysis. The agreement...

In addition, the ratio of positive charges on the nucleus to the number of orbital electrons is increased. Thus the effective nuclear charge is increased and the electrons are pulled in. A positive ion is therefore smaller than the corresponding atom and the more electrons removed (that is, ...
We have tried to obtain the E1 effective charges for both neutrons and protons from analyzing the decay scheme of the octupole vibrational states in the nuclei around 208Pb. The resulting values of e eff(E1) in the lead region for neutrons are appreciably smaller than those for protons. 关键...
Understanding the evolution of the nuclear charge radius is one of the long-standing challenges for nuclear theory. Recently, density functional theory calculations utilizing Fayans functionals have successfully reproduced the charge radii of a variety of exotic isotopes. However, difficulties in the isoto...
