excitation cross section

基本解釋

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(fā)截面的理論推導(dǎo)。
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截面是起源于該分子的剛性平面共軛結(jié)構(gòu)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，理論和實驗的一些偏離表明集體激發(fā)在C60光電離截面中起重要作用，考慮集體激發(fā)的改進(jìn)模型是必要的。
