Abstract
This work reports data of Stark widths and shifts of 37 Ne I lines that hav e been measured as functions of electron density and temperature in the ran ges (0.07-1.85)x 10(23) m(-3) and 13,900-20,700 K, respectively. A pulsed a re was used as a plasma source. The electron density was measured by single -wavelength interferometry using the 488.0 nm transition of an Argon ion la ser and has also been determined from Ha Stark broadening. The plasma tempe rature has been determined from the Boltzmann plot of Ne I lines and estima ted from the Saha law. Linear fits have been performed between Stark parame ters and electron density, and possible dependencies on temperature have be en checked. The measured parameters are compared with theoretical and exper imental data taken from the literature.
