Fourier-transform time-resolved spectroscopy of laser-induced breakdown of Cs vapor in a vacuum has been used for the measurement of atomic Cs emission spectra in the range with a resolution of . The and levels of Cs are observed. The dipole transition matrix elements (transition probabilities, oscillator, and line strengths) between the observed levels are calculated using quantum defect theory.

Comparison of QDT-Calculated -Values of Cs (this work) with the Experimental and ab initio Dirac–Hartree–Fock (DHF) Calculation Results Listed In [26] and the NIST Database [14] (for the and transitions)
Each of the seven spectral ranges, 800–1000, 1000–1300, 1200–1600, 1600–2000, 2000–3500, 4100–5000, and , has its own scale of arbitrary units for the emission intensity . Only the fractional parts are given for the NIST wavenumber values. The oscillator strengths are calculated using the QDT technique [Eq. (3)]
