Far‐vacuum‐ultraviolet transmission spectrum of uracil thin films

摘要

The method of directly subliming a thin film of specimen onto a scintillator has been used to extend its vacuum ultraviolet (VUV) transmission spectrum. With He light the far‐VUV transmission spectrum of a thin film of uracil from 4 to 21 eV (300–60 nm) has been obtained and is presented here. The results are in good agreement with VUV spectra previously obtained up to 10 eV and with electron energy loss measurements up to 21 eV.
