Scientific paper

On the question of whether intervening galaxies are responsible for the low-ionization absorption line systems found in the spectra of many quasars, an attempt is made to find whether most of the absorption arises in the halos or the disks of these galaxies. It is found that N(Ca II)/N(Na I) = 1.4 (+0.8, -0.6) in the gas from an intervening galaxy near the quasar 0446 - 208. This is suggestive of intervening disk material.
