Transmittance of a thin Saran film in the 45-584-Å wavelength region.
The transmittance of a free-standing Saran film, 4260 Å thick, has been measured by means of synchrotron radiation in the 45-584-Å wavelength region. The transmittance was calculated by means of the elemental composition of the film material as determined by x-ray photoelectron spectroscopy and the optical constants as derived from atomic-scattering factors. The calculated transmittance agreed with the measured transmittance in the 45-150-Å wavelength region. The calculated transmittance was significantly lower than that measured for the wavelength range 150-340 Å. This difference implies that molecular effects that are not accounted for by atomic-scattering factors become increasingly important at the longer wavelengths.
