J/AZh/71/37       Thermal Methanol from 33 Clouds at 48 GHz    (Slysh+, 1994)

Detection of Thermal Methanol Emission from 33 Hot and Cold Clouds at 48 GHz Slysh V.I., Bachiller R., Berulis I.I., Valtts I.E., Gomez-Gonzalez J., Kalenskii S.V. <Astron. Zh. 71, 37 (1994)> =1994AZh....71...37S
ADC_Keywords: Interstellar medium ; Masers ; Radio lines Keywords: Interstellar medium, molecular cloud: masers, radio lines Description: A search for thermal emission in the 10-00A+ methanol line was made at a frequency of 48.4GHz toward many celestial molecular clouds. The line was found in 33 clouds, and the methanol abundance varied over a large interval from 10-9 to 10-7. File Summary:
