Query: Stark Broadening of several Ar I Spectral Lines in the Visible Part of
  the Spectrum   In order to complete data on Stark broadening parameters for Ar I line in the
visible spectrum, we determined Stark widths and shifts due to electron,
proton, and ionized helium impacts, for nine lines (4191.0, 4259.4, 5912.1,
6043.2, 6045.0, 6752.9, 7503.9, 7514.6, 7724.2 {\AA}), using jK coupling and
semiclassical-perturbation theory. The obtained results will enter the STARK-B
database, which is a part of Virtual Atomic and Molecular Data Center.
