Detection of doubly deuterated ammonia in L134N.

Abstract (from CDS):

ND2H has been detected for the first time in the dense core of L134N, at the peak ammonia position. The abundance ratio [ND2H]/[NH2D] is 0.05, a slightly smaller value than the deuterium fractionation observed for ammonia [NH2D]/[NH3]∼0.1 (Tine et al., 2000, A&A, submit.). This is the second doubly deuterated species detected so far in the interstellar medium, and the first one in a cold dense core. The chemical processes leading to the formation of a significant amount of doubly deuterated ammonia ND2H need to be thorougly investigated.
