Scientific paper

The ammonia emission in the (J,K) = (2,2) and (3,3) inversion transitions has been mapped toward the Galactic star-forming region at l = 10.5 deg, b = 0.0 deg. Three distinct compact ammonia clouds are detected in a region of about 2 arcmin in diameter at given coordinates. The locations of these clouds with respect to the compact H II regions, their morphology and velocity structure, and the physical conditions within them are studied. Values are given for their sizes, peak rotational temperatures, peak NH3 column densities, H2 densities, and molecular masses.
