X‐ray diffraction measurements and subsequent data analyses have been carried out on liquid argon at five states in the density range of 0.91–1.35 g/cc and temperature range of 127–143 °K. Duplicate measurements were made on all states. These

A version of the Steele‐Pecora equation suitable for use with diatomic molecules has been derived. Substitution of chlorine scattering factor coefficients and Percus‐Yevick distribution functions into this equation led to the determination of tot

The effects of collimation distortion on the measured diffraction curves from `amorphous' solids and liquids are discussed. It is shown how the parameters governing the range of angular divergence may be obtained and how the `permissible' range of sc

Numerical estimates of double scattering of X-rays have been made in cylindrical and parallel-plate geometries for fluid argon in two states. For the cylindrical geometry the ratio of double scattering to single scattering is ~0.01 and independent of

The viscosity of xenon has been measured along 10 isochores and the viscosity of ethane along five isochores in the region of the gas‐liquid critical point. The viscometer was a torsionally oscillating quartz cylinder, which generates a viscous wav

We have studied the light scattered from amorphous polymethylmethacrylate (PMMA) using the correlation technique for a range of temperatures from 6 to 165 °C encompassing the glass transition temperature (Tg∼120 °C). The data were analyzed in ter

Some experimental and theoretical comparisons have been made of the effectiveness of four techniques which have been commonly used for monochromatizing X-radiation for use in diffraction studies of liquids: monochromator crystals, curved or flat; fl-

Use of radial distribution data, g(r), to compute a coordination number, N 1, for liquids is discussed for four methods: A, symmetrizing the first peak in rg(r); B, symmetrizing the first peak in r2g(r); C, decomposition of r2g(r) into shells; and D,

By means of the principle of minimum deviation, the refractive index was determined for argon, methane, and carbon tetrafluoride as saturated liquids from the triple point to the critical point. For argon, some measurements were also made on the satu
