The impact-broadened linewidth of the Al II 467-nm line is compared wi
th theory for ions embedded in plasma dense enough that the impact app
roximation becomes questionable, and where electron-electron correlati
ons may be non-negligible. No significant difference in linewidth is f
ound for plasmas in which the plasma parameter g is as large as 0.8.
