FTIR laboratory measurement of He I spectra in the 6.5-14 mu m spectral range: Transitions involving f, g, h, and i states

Popis výsledku v původním jazyce

Time-resolved infrared emission spectra of atomic helium have been measured using a high-resolution Fourier transform spectrometer in the spectral range of 70 0-1500 0 cm(-1) with a maximum resolution of 0.01 cm(-1). A total of 74 spectral lines have been observed, of which 47 lines are detected for the first time. Most of the observed transitions are from highly excited levels (n = 8, 7 and 6). The time profiles of the spectral line's emission intensities observed under the current experimental conditions have been plotted, and the decay times have been obtained. The level energy values are extracted from the list of spectral lines, and their consistency is justified by the obtained ionization potential of the He atom and the dipole polarizability of He+.
