AI 中文摘要
氦纳米液滴是阐明电离辐射在凝聚态物质中诱导的次级过程的理想测试平台。本研究在极紫外区域探究大氦纳米液滴的光电离电子光谱,其中光电子会与液滴内的氦原子发生多次非弹性碰撞。通过结合光子能量、纳米液滴尺寸的依赖关系,并与简单数值模拟对比,识别出特征性的电子能量损失特征,同时讨论了最小化电子与氦纳米液滴散射的条件。
英文摘要
Helium nanodroplets are ideal testbeds for elucidating secondary processes induced by ionizing radiation in condensed matter. Here we study photoionization electron spectra of large He nanodroplets in the extreme ultraviolet region, where photoelectrons undergo multiple inelastic collisions with He atoms in the nanodroplets. The resulting characteristic electron energy-loss features are identified by their dependence on photon energy and nanodroplet size and by comparison with a simple numerical simulation. Conditions for minimizing electron scattering with the He nanodroplets are discussed.
