+The //J// = 1 − 0 transition of <sup>36</sup>ArH<sup>+</sup> was detected with the APEX 12 m dish toward the nearby galaxies NGC 253, NGC 4945, and Arp 220. The molecular fraction of the gas traced by ArH<sup>+</sup> was estimated to be ~10<sup>−3</sup> and that it resides in gas volumes with low electon densities.\\
