“…[1][2][3][4][5][6][7][8][9][10][11][12][13] In the most recent study, the second dielectric virial coefficient of argon B ⑀ (T) was measured for several temperatures by Huot and Bose. 11 Previous measurements are due to Vidal and Lallemand, 5 Bose et al, 3,9 Johnston et al, 1 Orcutt and Cole 2 and Proffitt et al 7 Buckingham and Graham 4 , Burns et al, 8 Coulon et al, 6 Achtermann et al 10 and Hohm 13 determined the second refractivity virial coefficient B R (,T). The second Kerr virial coefficient B K (,T) has been estimated among others by Dunmur et al, 14,15 Buckingham and Dunmur,16 and recently by Shelton and Palubinskas.…”

Ab initio calculation of the interaction induced polarizability and hyperpolarizability in He 2 and Ar 2 Coupled cluster calculations of the frequency-dependent second hyperpolarizabilities of Ne, Ar, N 2 , and CH 4The frequency-dependent interaction induced polarizability and second hyperpolarizability of the argon dimer are computed for a range of internuclear distances employing the coupled cluster singles and doubles response approach. The frequency dependence of the interaction-induced properties is treated through second order in the frequency arguments using expansions in Cauchy moments and hyperpolarizability dispersion coefficients. The dielectric, the refractivity, the Kerr and the hyperpolarizability second virial coefficients are computed for a range of temperatures employing a recent accurate ab initio potential for the ground state of the argon dimer. For most of the computed virial coefficients good agreement is obtained between the present ab initio results and the available experimental data.

We report the room-temperature isotropic collision-induced light scattering spectrum of Ne-Ne over a wide interval of Raman shifts, and we compare it with the only available experimental spectrum for that system as well as with spectra calculated quantum-mechanically with the employ of advanced ab initio-computed data for the incremental mean polarizability. The spectral range previously limited to 170 cm(-1) is now extended to 485 cm(-1) allowing us to successfully solve the inverse-scattering problem toward an analytic model for the mean polarizability that perfectly matches our measurements. We also report the depolarization ratio of the scattering process, lingering over the usefulness of this property for more stringent checks between the various polarizability models.

“…Data for the refractive index of argon for the He-Ne laser and semiconductor laser are essential for practical measurements at different temperatures and pressures. According to the literature [5][6][7][8][9][10][11], the values of the refractive index for argon are given at 0 • C and atmospheric pressure. The refractive index can be calculated by two methods.…”

“…In this paper, the refractivity virial coefficient method was used to calculate all refractive index data for argon. By comparing the value of the refractivity virial coefficients in the literature [5][6][7][8][9][10][11], the refractivity virial coefficient for argon is slightly affected by temperature, so it is reasonable that the virial coefficient is approximated as a constant. The refractive index of argon at 273.16 K for the wavelength 633 nm is given by this equation,…”

The length is one of the key parameters for a cylindrical acoustic resonator used for measurement of the Boltzmann constant. A research project has been conducted in the National Institute of Metrology (NIM), China, for the re-determination of the Boltzmann constant with a fixed-path cylindrical acoustic resonator. This paper describes the procedure for the length determination. The excess fraction method was applied to accurately obtain the length of the resonator. This method is performed in a two-step procedure. First, the length is coarsely determined as L 1 with an uncertainty of 1.5 µm in the length division of NIM. Second, the result of the coarse measurement is further interpolated by the dual wavelength laser interferometer with a resolution of 1 nm, which is composed of a 633 nm He-Ne laser and a 657 nm semiconductor laser. A Michelson wavemeter has been constructed for calibration of the wavelength of the semiconductor laser. The length variation of the resonator has to be measured from room temperature to the triple point of water (TPW). As a result, the laser interferometer can be also used as a precise dilatometer. The result and the measurement uncertainty of the length measurement are given in this paper.
