    The excited levels argon (Ar*;1 s5, 1 s4, 1 s3 and 1 s2) are populated by means of a DC discharge in argon-nitrogen mixtures. The densities of Ar* (nj;j=5, 4, 3, 2) are measured by optical absorption techniques.The deactivation cross-sections (Qjo) of Ar* (1sj) by N2 are determined from the dependence of nj on nitrogen fraction and are 0.75±0.10, 2.2±1.1, 0.32± 0.06 and <3.3 Å2 for the 1 s5, 1 s4, 1 s3 and 1 s2 levels respectively.
    The (0, 2) band of N2 second positive system is observed at the same time and it is clarified that Ar* excites the N2 (C3IIu), υ'=0 level which is characteristic of the nonequilibrium rotational populations such as the enhanced structure and alternating population.The ratios of the excitation rates of the N2 (C3IIu), υ'=0 level by electrons and Ar* are obtained from analysis of the nonequilibrium rotational populations for different nitrogen fractions, and explained by considering nj and Qjo.The cross-section of rotational relaxation (30±10 Å2) is also obtained from study of the dependence of alternating populations upon the pressure.
    The collisional mechanisms between Ar* and N2 are discussed mainly on the basis of the one-step mechanism consisted of the ArN2* complex proposed by Setser and Stedman.

  • Light Absorption and Scattering by Colloidal Na in NaCl

    Mie's theory has been applied to colloidal sodium in NaCl. In the course of the calculation, the optical constants of metallic sodium are corrected for the size of the colloidal particles. The contributions of the electric and magnetic partial oscillations to the total extinction (spectra) are analized.A discussion is given by comparing the calculated results with the experimental spectra reported by several authors.

  • Accuracy and Effective Temperature Factor in X-ray Analysis

    The importance of the effective temperature factor in X-ray analysis was shown by presenting the results of measurement of the effective Debye parameter Be f f on some crystalline samples.Calcium fluoride precipitated from Ca (OH) 2 by HF had three times larger value of Be f f than the commercial reagent grade one.This value corresponded to the value after grinding of reagent grade CaF2 for more than 20 hrs.Rutile formed by the phase transformation from anatase with very fine grain was found to have relatively large value of Be f f at the beginning of transformation.It was shown that very large error in the quantity of the crystalline phase might be introduced from the neglect of the effective temperature factor if intensity of the diffraction line at high angle side was used.It was also shown to obtain more reliable results on the ion distribution in spinels (GeCo2O4 and CoAl2O4) by finding the one gave the best linearity between log (Iobs/Icalc) and (sin 2θ/λ2).By this revised method, the effect of the difference in the effective temperature factor from specimen to specimen on the conclusion can be neglected.
