将液体微射流技术与速度图成像技术相结合，构建了一种新型的液体微射流光电子成像光谱仪。这种新的方法使我们能够同时测量从高挥发性液体溶液中产生的光电子的能量和角分布。通过记录2-呋喃甲醛水溶液的光电子图像，验证了该光谱仪的性能。据我们所知，这是第一次液体水溶液的PEI成功。
A new liquid-microjet photoelectron imaging (PEI) spectrometer has been constructed that combines the liquid-microjet technique with velocity-map imaging. This novel method enables us to simultaneously measure the energy and angular distributions of the photoelectrons produced from highly volatile liquid solutions. The capability of the spectrometer has been demonstrated by recording the photoelectron image of the aqueous 2-furfural. To our knowledge, this is the first time that the PEI of liquid aqueous solutions has succeeded.
