In an attempt to improve the accuracy of reflectance determinations, particularly from high vapor pressure samples, we have built and tested a double ionization chamebr which measures the ionization from a photon beam in the vapor or added gas before

Our apparatus has been modified to permit measurements of absolute photoemission as well as reflectance of liquids in the vacuum UV. Photon fluxes are determined by filling the tandem ion chambers with argon. An electrometer is connected to the sampl

Refractive indices of bovine serum albumin solutions in saline and in 2-chloro ethanol are measured for the spectral region 1770–10000 A by a reflectance method. A procedure for the determination of a dispersion formula for binary mixtures is devel

The reflectance of liquids squalane and squalene between 2 and 25 eV have been determined by closed cell double ionization chamber methods. Kramers–Kronig analysis of the data gives optical functions from which are calculated the dielectric functio

The optical properties of the liquids normal tetradecane (C14H30) and normal heptadecane (C17H36) were determined for photon energies from 4 to 25 eV. Near normal incidence (15 °) reflectance measurements were analyzed by a Kramers–Kronig method t

The optical properties of Kapton type H polyimide film, obtained from reflectance measurements, are presented for photon energies from 0.5 to 70 eV. Equations for the energy‐loss function, with parameters fixed by the optical data, are employed to

A vacuum uv reflectometer is described which makes use of a highly reproducible stepping motor drive system. The concentric shaft design eliminates many alignment problems common to other systems and makes possible a single flange mounting. The pulse

Measurements of the optical properties of liquid water were extended in the vacuum ultraviolet up to an energy of 25.6 eV. The indices of refraction and dielectric functions were obtained by a Kramers‐Kronig analysis using reflectances measured in
