X-ray photo-desorption of NH3 and N2 from ammonia ices: Mechanisms and yields in protoplanetary disks

Open Access

Table 1

Desorption yields in molecules per incident photon at 430 eV, for a photon fluence of ≤2 × 10¹⁶ ph cm⁻² (see red curves in Fig. 4).

T (K)	NH₃ (10⁻²)	N₂ (10⁻¹)
23	3.7 ± 0.3	1.7 ± 0.1^(a)
75	3.7 ± 0.3	…

Notes. Calculated as the average of five values around 430 eV, the error bars correspond to the standard deviation of said values from the average (related to the noise observed in the m/z channel). ^(a)Value for a fluence between 2 × 10¹⁶−4 × 10¹⁶ ph cm⁻² (see text).
