摘要：

Frequency changes of plasma oscillations in the kHz range (pseudosonic waves) induced by resonant laser excitation of species in low-pressure de discharges are used for detection of (21)Ne in pure Ne. The analytical capability and the limitations of this novel spectrochemical technique have been studied in noble gas discharges. (C) 1998 Elsevier Science B.V.
