摘要：

The quantum defect Green function formalism is applied to calculate the dynamic scalar and tensor polarizabilities of some atoms in their excited states (2(1)S, 2(1)S, 2(1)P and 2(3)P for He, 2(1)P and 2(3)P for Be, 3(3)P for Mg and 4(3)P for Ca). Experimental and calculated oscillator strength values were used to provide an account for low-excited states (reduce-adding correction of the Green function) while the high-excited and continuum states are accounted semi-analytically. The calculated polarizability values are in good (within several per cent) agreement with the available experimental data and the ab initio numerical data.
