THE MEASUREMENT OF THE VAPOR PRESSURE OF ATOMIC SPECIES FROM SPECTROPHOTOMETRIC MEASUREMENTS OF THE ABSORPTION OF RESONANCE LINES. II. THE OSCILLATOR STRENGTH OF THE CU3247 LINE.
Abstract
The oscillator strength of the Cu3247 resonance line was obtained from the experimentally determined absorption coefficient at its center. This resonance line was generated in a hollow cathode discharge tube operated at liquid nitrogen temperature and its absorption by an amount of copper vapor of known length and density was measured spectrophotometrically. The value of f was calculated from this measured absorption by taking into account the effect of Doppler and pressure broadening and of the hyperfine structure of the line. The copper vapor consisted of the equilibrium vapor over copper in an isothermal cell, in the presence of a sufficient density of inert gas to diffusion limit the effective cell length. The reported result f = 0.32 is compared with literature values, and its probable error is estimated. (Author)
