Molecular processes in expanding plasmas : a laser spectroscopic study

  title={Molecular processes in expanding plasmas : a laser spectroscopic study},
Fabry-Pérot line profile measurements have been used to obtain heavy partiele temperatures and electron densities for an ex panding cascaded are plasma in argon. This was done for the argon 415.9 nm and 696.5 nm neutral lines as a function of the distance from the onset of the expansion. Temperatures in the range of 2,000-12,000 K were obtained. The electron density in the beginning of the expansion appeared to be 5.6x 1021 m-3 The 696.5 nm Jine profiles appeared to be asymmetrie because of… CONTINUE READING
