| Abstract: | Methylidyne (CH) line observations were obtained at Algonquin from the diffuse molecular cloud envelope at G180.9+4.1, sandwiched between the optical H II region S241 and the molecular cloud core at G180.8+4.0. An analysis of these observations yields several of the envelope parameters, notably a CH column density of 2×1013 cm–2, a microturbulent velocity of 2.6 km s–1, and a total space density of 40 cm–3. |
