论文摘要
飞秒极端的紫外线波数据包干涉法(XUV-WPI)用于研究Hene Dimer中的谐振原子间库仑衰变(ICD)。使用XUV相循环方案满足了对分子梁目标振动XUV-WPI的相位稳定性和灵敏度的高需求。检测到的量子干扰物表现出振动的脱位和重新定位特征,以及分配给ICD过程的超快脱位。傅立叶分析揭示了具有高分辨率的分子吸收光谱。展示的实验显示了具有高时间和光谱分辨率的超快ICD过程实时分析的有希望的途径。
Femtosecond extreme ultraviolet wave packet interferometry (XUV-WPI) was applied to study resonant inter-atomic Coulombic decay (ICD) in the HeNe dimer. The high demands on phase stability and sensitivity for vibronic XUV-WPI of molecular-beam targets are met using an XUV phase-cycling scheme. The detected quantum interferences exhibit vibronic dephasing and rephasing signatures along with an ultrafast decoherence assigned to the ICD process. A Fourier analysis reveals the molecular absorption spectrum with high resolution. The demonstrated experiment shows a promising route for the real-time analysis of ultrafast ICD processes with both high temporal and spectral resolution.
