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

Open Access

Fig. 4

NH₃ and N₂ desorption yields from ammonia ices at 23 and 75 K, in molecules per incident photon. The TEYs from the lower fluence experiments (≤2 × 10¹⁶ ph cm⁻², black dashed curves) are shown in an arbitrary scale to match the NH₃ desorption in the ionisation continuum. The colour code is the same as in Fig. 2.
