EXPERIMENTAL STARK WIDTHS AND SHIFTS AND TRANSITION-PROBABILITIES OF SEVERAL XE-II LINES

This work reports measured Stark widths and shifts, and transition pro babilities for a large number of Xe II spectral lines. A pulsed arc wa s used as a plasma source. The electron density, determined by interfe rometry at one wavelength, and simultaneously by the Stark broadening of the 5016-angstrom He I line, covers a range of (0.2-1.8) x 10(23) m -3. A method is proposed to find simultaneously the plasma temperature and the transition probabilities from relative intensity measurements of spectral lines. Electron temperatures are in the range of 11 000-1 6 000 K. The measured parameters are compared with experimental data t aken from the literature.
