Stark widths and shifts of six CII, three CIII and two CIV spectral lines have been measured in a linear pinch discharge plasma and compared with available experimental and theoretical data. Electron density, (0.86−1.64)×10 m, was determined by single wavelength laser interferometry using the visible 632.8 nm transition of He-Ne laser. The electron temperature of 38000 K was derived from the Boltzmann slope of several CII spectral lines, and ratios of several CII to CIII spectral lines. The stark widths ( w) dependence on: (i) the upper-level ionization potential ( I) of corresponding lines; (ii) net charge ( z) of the emitter core seen by the optical electron undergoing transition, and (iii) electron temperature ( T) was found to be of the form: w= az T I. However, it should be noticed that the essential role in the obtained trends belongs to the energy of the emitter core. The established overall trend is used to predict Stark widths of uninvestigated spectral lines originating from the given transition arrays. [ABSTRACT FROM AUTHOR] |
