Variation of photoabsorption cross section of atomic silver from isolated to condensed conditions 下载免费PDF全文
The influence of the local-field on the photoabsorption cross section of the atomic silver is studied in detail by using the Clausius-Mossotti (CM) model and the Onsager model separately. The variations of the photoabsorption cross section of atomic silver with number density and radius of the environmental interaction cavity are studied systematically by using more general expressions for the photoabsorption cross sections, proposed by Sun et al recently. It has proved to be reasonable to model the optical response properties of bulky material by coupling the property of isolated atom with the environmental effects in the present work. 相似文献

从Q函数的原始定义出发直接导出了压缩态下的Q函数,此法比从两变量的高斯分布导出压缩态下的Q函数的方法更简单自然,而且有助于理解Q函数的性质. 相似文献

在相互作用绘景中,得到了两模微波激射器的腔模与注入其内的Λ型三能级原子构成的相互作用系统的演化算符的矩阵表示,以及该系统的态函数随时间的演化关系,在此基础上导出了原子布居数随时间的演化关系,由此可进一步研究布居数的振荡、反转和捕获等问题. 相似文献
