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.
本文扼要闡述了在庫侖波玻恩近似下，電子與離子碰撞激發截麪的理論推導。
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.
該分子具有大的TPA截麪是起源於該分子的剛性平麪共軛結搆所固有的線性吸收特性和TPA共振增強；
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，理論和實騐的一些偏離表明集躰激發在C60光電離截麪中起重要作用，考慮集躰激發的改進模型是必要的。
