论文摘要
我们介绍了嵌入超氟氦纳米体中的分子的单光子极限光电谱（PES）的第一个测量。将冠状动脉的PES与气相和固相PES进行了比较，以及通过电荷转移和通过电离或激发氦气产生的嵌入冠状动脉的电子光谱。 He-Droplet PES与固相之一的相似之处表明，主要是COR簇是光电离的。相比之下，He-Droplet Penning-Iromation电子光谱几乎没有结构，表明He液滴对电离过程的强烈扰动。这些结果铺平了嵌入在氦纳米光中的簇和分子络合物的极端紫外光谱光谱（UPS）的道路。
We present the first measurement of a one-photon extreme-ultraviolet photoelectron spectrum (PES) of molecules embedded in superfluid helium nanodroplets. The PES of coronene is compared to gas phase and the solid phase PES, and to electron spectra of embedded coronene generated by charge transfer and Penning ionization through ionized or excited helium. The resemblence of the He-droplet PES to the one of the solid phase indicates that mostly Cor clusters are photoionized. In contrast, the He-droplet Penning-ionization electron spectrum is nearly structureless, indicating strong perturbation of the ionization process by the He droplet. These results pave the way to extreme ultraviolet photoelectron spectroscopy (UPS) of clusters and molecular complexes embedded in helium nanodroplets.
