description: This paper presents the results of an analysis of a number of physical conditions: density, thermal pressure, ultraviolet radiation field intensity and excitation temperature in the interstellar medium of our Galaxy containing Hâ and CO. Our measurements are based on fitting to the observed population of the rotational levels Hâ, CO and fine structure levels CI using numerical model grids calculated using the code PDR Meudon. From the data set obtained by the Far Ultraviolet Spectroscopic Explorer (FUSE) telescope, 15 absorption systems Hâ along the line of sight of the stars in the Milky Way galaxy were selected for which the physical quantities were analyzed. In the space of parameters I uv-n (the intensity of the UV background and the concentration of atoms / molecules) in the case of atomic carbon CI is found the effect of shielding molecular clouds, which consists in the following: with an increase in the intensity of the ultraviolet radiation field, the concentration remains unchanged. A detailed consideration of this effect will be carried out in joint works under the leadership of V.V. Klimenko.
