Abstract

Little is known about the interaction of extreme ultraviolet light (EUV) with materials. This project is a beginning step to filling the information void. My wavelength, 584 Å, is a dominant He I line in the EUV, the 1s 2p to 1s2 transition. The electron gas model predicts that the more electrons a material has the greater its reflectance should be, which implies that U may reflect more than most substances in this region, because of its high atomic number.1 One of the obstacles to research in the EUV is that light is so readily absorbed by everything including air, so all measurements have to be made in vacuum and the signals are generally weak. Another obstacle is the lack of information itself, which complicates sources and detectors.
