Abstract:
Using a modified semiempirical approach, we have calculated Stark
broadening full widths at half maximum for 25 OII multiplets for
temperatures from 5000K up to 80000K using the needed oscillator
strengths from the sophisticated atomic structure data base TOPbase.
Then we compared our results with experimental data for 41 OII
spectral lines and with the available semi-classical calculations to
test the applied method and the accuracy of the results obtained.
