Notes:
A simple and sensitive detection method of Xe(1s5) excited atoms in the vicinity of a discharge wall with laser-collision induced fluorescence (LCIF) produced by evanescent wave absorption is proposed. The signal to noise (S/N) ratio was 102. The hyperfine structure (hfs) in the Xe LCIF spectra induced by resonant absorption of Xe(1s5→2p6) was confirmed to be identical with the hfs in laser absorption spectra, although the detection point (xPD) on the discharge wall was chosen independently of the position of the EW absorption (xEW). The insignificantly large fluorescence, which appeared for incident light angles to a prism larger than 4.8°, is explained by the fact that the refracted light emerged in a plasma. The Xe(1s5) number density in a dc Xe discharge, although roughly estimated, on the tube wall between the electrodes is presented. © 2001 American Institute of Physics.
