This paper briefly describes the theoretical deduction of the crosssection of electron -ion impact excitation in Coulomb -born approximation.
本文扼要阐述了在库仑波玻恩近似下,电子与离子碰撞激发截面的理论推导。

The importance of the virtual excitation in calculating the differential crosssection of the elastic is discussed.
发现在弹性散射中虚激发的贡献是重要的。

The large TPA crosssection may result from the intensive linear absorbance of the molecule due to its conjugate rigid plane structure, and the two-photon resonance excitation condition.
