A review of oscillator strengths for lines of Cu I

Abstract

New determinations of oscilla tor strengths mad e by Kock and Richter provide for the first time referen ce standards which permit the adjustment of five previous se ts of meas ureme nts to an improv ed scale of absolute osc illator st re ngth s for lin es of Cu I. Critical disc uss ions of th e se veral sets of meas ure· ments and a co nsistent li st of values for 272 lin es in th e region 2024 to 8092 A are prese nted.Key word s : Atomic s pectra; coppe r; C u I ; os c ill ator strength s; spect ral lin es of C u I.

“…The temporal dynamics of several lines is shown in Figure 2.

Their decay time, T , values are therefore estimated in Table 3 in a rough approximation; it is seen from this table that for essentially non-exponential decays the uncertainity ∆T is of the same order of magnitude as T itself.…”

Spectroscopic characterization of hypervelocity jetting: Comparison with a standard theory

“…These lines are covered by Corliss [1970], and the same data are listed by Fu et al [ 1995]. These particular lines are often located very close to other Cu I emission lines and cannot be resolved with the current configuration of our spectrometers, which are intended to capture a wide range of wavelength with moderate spectral resolution.…”

Stark broadening calculations of neutral copper spectral lines and temperature dependence

“…In our calculations, the energy levels and oscillator strengths were taken from Corliss [34] (also given in the critical compilation of Fu et al [35], where they are estimated as the best values for these lines).…”
