Abstract:
With the development of space-borne spectroscopy, spectral line
parameters for a large number of lines become of increasing interest
for astrophysics. To provide Stark broadening data for ion lines from
complex spectra, we present here calculated Stark widths for 37 Kr II
lines from the 5s-5p transition. The calculations were performed by
using a modified semiempirical approach. The obtained Stark widths are
on average in satisfactory agreement with available experimental data.

Notes: *: Only experimental data from Bertuccelli & Di Rocco
(1993, Phys. Scr. 47, 747). The value of <wexp/w{th}> is
the averaged ratio between all experimental results for the
considered line widths and our theoretical Stark widths,
and <w/w_th> is the averaged ratio for the considered
calculation in the Table.
