• 論文の詳細を見る

• Various features of the effect of alignment in the upper-level population on the observed emission-line intensity, i.e., the spatially-anisotropic intensity distribution and polarization, are demonstrated using laser-induced fluorescence spectroscopy on the neon 2p^53s-2p^53p transitions in a plasma. Disalignment by atomic collision is observed on the 2p_2 level, and its rate coefficient is determined as (1.70±0.03)×IO_<-10>cm^3s^<-1>. The case of hyperfine-structure lines is discussed. Polarization is observed in the hydrogen Balmer α line fluorescence following the laser excitation of the same transition. Conditions are given under which the alignment effect is eliminated or can be neglected. Cases of unpolarized-light excitation and high-intensity excitation are discussed.
