Potassium spectra in the 700?7000 cm-1 domain: Transitions involving f-, g-, and h-states

Popis výsledku v původním jazyce

Context. The infrared (IR) range is becoming increasingly important to astronomical studies of cool or dust-obscured objects, such as dwarfs, disks, or planets, and in the extended atmospheres of evolved stars. A general drawback of the IR spectral region is the much lower number of atomic lines available (relative to the visible and ultraviolet ranges). Aims. We attempt to obtain new laboratory spectra to help us identify spectral lines in the IR. This may result in the discovery of new excited atomiclevels that are difficult to compute theoretically with high accuracy, hence can be determined solely from IR lines. Methods. The K vapor was formed through the ablation of the KI (potassium iodide) target by a high-repetition-rate (1.0 kHz) pulsed nanosecond ArF laser (? = 193 nm, output energy of 15 mJ) in a vacuum (10-2 Torr). The time-resolved emission spectrum of the neutral atomic potassium (K?i) was recorded in the 700?7000 cm-1 region using the Fourier transform infrared spectros
