Deuterated ammonia in Galactic massive star-forming regions

Deuterated ammonia in Galactic massive star-forming regions

We present sensitive observations of NH2D111 a-101s at 110.153 599 GHz toward 50 Galactic massive star-forming regions with the Institut de Radioastronomie Millimétrique (IRAM) 30-m telescope. The NH2D111 a-101s transition is detected toward 36 objects, yielding a detection rate of 72 per cent. Col...
