Abstract
High resolution time-resolved Fourier-transform infrared spectroscopy is be applied for observations of the emission arising after irradiation of a metal and metal oxides targets with a pulsed nanosecond ArF (λ = 193 nm) laser. The infrared emission spectra will be studied in the 800–8000 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> spectral region. Although the spectra of the atoms were studied in various frequency ranges, our study points to the existence of spectral lines, which have not yet been observed. While the visible spectral lines are due to the transitions involving the ground and low-excited states, the IR lines in atoms correspond to the transitions between highly excited (Rydberg) levels. The transition probabilities and oscillator strengths for all transitions involving the reported levels are calculated.
