Detection of 13 CN in three galactic sources.
Abstract
The authors report the detection of the isotopic radical 13CN in Sagittarius B2, Orion A and IRC+10216. 13CN column densities are derived and compared with previous observations of CN in the same sources. Isotopic ratios 12CN/13CN are obtained and discussed, in agreement with other determinations.
