Calculation Of Multipole Polarizability And Dispersion Coefficients For Helium

Main work of this paper is to establish the calculation of helium atom multipolar dynamic polarization and the interaction between the dispersion coefficient of two kinds of stability of the variational method, in a single electron potential model(the weakest bound electron potential model) based on the stability of the variational method and on the basis of the double electron configurations of helium atom the stability of the variational method. More specifically:This paper by the weakest bound electron potential model theory as the foundation, established the calculation of helium atom multipolar dynamic polarization and the interaction between the dispersion coefficient of the stability of the variational method. Derived by the method of matrix involved in the dollar and the analytical expression of linear equations. As an application, the concrete calculation of the ground state of helium atom polarization and the dispersion coefficient of two bodies, the calculated results and the results were compared with other methods, the data are basically identical.Considering the actual configuration of helium atom is double electron configurations, based on the double electron configuration to set up a calculation of helium atom polarization rate and the interaction between the dispersion coefficient of the stability of the variational method, alkaline earth metal atoms for further research of polarizability and the interaction between the dispersion coefficient, the more meaningful. Therefore, this article further on the basis of the double electron configuration set up calculation of helium atom multipolar dynamic polarization and the interaction between the dispersion coefficient of the stability of the variational method. Derived by the method of complex matrix involved in the yuan and the analytical expression of the system of linear equations calculation of ground state of helium atom polarization rate, and the calculated results and the results were compared with other methods, the data are basically identical.Due to the stable variational method has the characteristics of high precision and fast convergent, and alkaline earth metal atom valence electron configuration and helium atoms are similar, the work may calculate polarization and atomic interaction alkaline earth metal dispersion coefficient provides a new way. At the same time for the research of other atoms dynamic polarization and the dispersion coefficient to provide the reference.
