excitation cross section

基本解释

This paper briefly describes the theoretical deduction of the cross section 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 large TPA cross section may result from the intensive linear absorbance of the molecule due to its conjugate rigid plane structure, and the two-photon resonance excitation condition.
该分子具有大的TPA截面是起源于该分子的刚性平面共轭结构所固有的线性吸收特性和TPA共振增强；
The important role of collective excitation in the photoionization cross-section of C60 is suggested. Improvement of the model by taking into account the collective excitation is indicated.
然而，理论和实验的一些偏离表明集体激发在C60光电离截面中起重要作用，考虑集体激发的改进模型是必要的。
