用RKR(Rydberg-Kleinn-Rees)方法计算了Cs2分子的X1∑ g和A1∑ u的势能曲线,求解了Cs2分子核运动的径向薛定谔方程,获得X态与A态间跃迁的Franck-Condon因子和1.06 μm附近区域的吸收光谱,并与实验测得的吸收光谱作了比较,两者相当符合。
The reflection and transmittance of s- and p-polarized lights should be treated separately at nonzero angle incidence. By choosing two special film materials whose refractive indices meet the Brewster condition in a given incident angle, the reflection of

Te(Ⅳ), Se(Ⅳ), V(Ⅲ), Nb(Ⅴ) and Ta(Ⅴ) complexes of indole-3-acetic acid (IAAH) ligand were synthesized, characterized by elemental analysis and various spectroscopic techniques like, IR, 1H-NMR, X-ray powder diffraction, UV-Visible, thermogravime
利用紫外飞秒激光光谱技术研究了Al2O3/SiO2高反射膜内的超快载流子动力学。通过实验, 发现该反射膜Al2O3层的载流子动力学在紫外反射膜的激光诱导损伤中起着至关重要的作用。通过泵浦-探测实验, 发现紫外飞秒激光与光学薄膜作用后, 光学薄膜反射率有所下降, 且探测光反射率变化的峰值在约2.3 ps的时间内从417 nm左右转移到402 nm左右。为了更好的解释激光诱导载流子动力学, 一个具体的理论模型被提出来, 该模型指出导带自由电子弛豫过程中与晶格相互作用, 产生距导带一个光子能量的中间缺陷态, 其
The measurement of an extremely small magneto-optical polarization rotation angle with high sensitivity is integral to many scientific and technological applications. In this Letter, we have presented a technique based on Faraday modulation combined with
The laser-induced breakdown spectroscopy is used to analyze the lead content in soils. The analyzed spectral line profile is fitted by Lorentzian function for determining the background and the full-width at half-maximum (FWHM) intensity of spectral line.
We present an investigation on the propagation properties of the chirped Airy vortex (CAiV) beams through slabs of left-handed materials (LHMs) and right-handed materials (RHMs). We discuss the influence of chirped parameter
