Abstract
For 61 stars whose interstellar Lα absorption was observed by OAO-2, the average relation of H i column density to B — V color excess is equal to 5 × 1021 atoms cm−2 mag−1. For a recent dust grain model this value implies that the density ratio <ρ HI/ρdust> ≈ 100. A good correlation was found for deviations in the measurements ofN hi and E(B — V) from their mean values expected over the distances to the different stars, indicating an association of H i gas with dust.
