Discussion about the Physical Meaning of Potential Function in the Weakest Bound Electron Potential Model Theory

From the viewpoint of screen effect, penetration effect and polarization effect, the potential function of the Weakest Bound Electron Potential Model theory (abbreviated as WBEPM theory) is discussed. After deducing, the physical meaning of the effective potential suggested ithe theory is concluded that the first term in the potential function is the potential felt by thweakest bound electron in the central field of effective nuclear charge +Z′e, and the second term is the potential felt by the weakest bound electron in the dipole field produced by the polarizatio of the core composed of non-weakest bound electrons and nucleus.
