Experimental transition probabilities of several NeI lines

This work reports a collection of 28 transition probabilities of lines in the spectral region 590–815 nm, corresponding to the most intense Ne I transitions (3p-3s, 3d-3p), all measured in an emission experiment. Relative intensity measurements have been made on a pulsed discharge lamp and the absolute Aki values have been obtained by using an extensive set of data taken from the literature. The electron density has been determined by one-wavelength interferometry and ranges from 0.1 to 1.8 × 1023m−3 in the plasma. The NeI excitation temperature (11000–21000 K) has been determined from the Boltzmann-plot of the lines and also estimated by the Saha law.
