摘要
本文提出了一种测量原子和分子的双光子吸收截面的新方法——饱和光电流光谱法。在二能级模型的基础上,从实验上首次测定放电管中Ne原子的1S_5—4d″_1两能级间的双光子吸收截面,与理论计算结果颇为一致。
A new method that uses saturated optogalvanic spectroscopy to measure two-photon absorption cross section of atoms and molecules is presented. The two-photon absorption cross section of 1s_5-4d'_1 transition in Ne in a discharge tubehas for the first time been determinated experimentally. The experimental resultsare in agreement, with theoretical ones, obtained based on a two-level model.
