PHOTOELECTRON MEASURING DEVICE

摘要

A photoelectron measuring device capable of handling a sample in the atmosphere. The photoelectron measuring device which allows a ultraviolet ray generating device (1) to apply a ultraviolet ray to a sample (S) with its wavelength being changed and detects a wavelength at which a photoelectron is first emitted from the sample (S), wherein a portion up to an emission port (2) is kept under a non-oxygen environment, and a sample table (4) is so located as to keep the distance between the emission port (2) and the sample (S) surface at up to 7 mm.
