Comparison between Rc (a), the reaction probability P(b) (b), and the ionization cross section contribution πb2P(b) (c) evaluated as a function of ℓ/b, at fixed \({E}_{{coll}}\,\)= 1.0 meV. Note that for such \({E}_{{coll}}\) value the semiclassical relation \(b\simeq \frac{\ell }{k}\) provides b(Å) \(\simeq \frac{\ell }{2.097}\) for ammonia, b(Å) \(\simeq \frac{\ell }{2.526}\) for Ar and b(Å) \(\simeq \frac{\ell }{2.362}\) for N2. For the reaction of ammonia, only the channel leading to the formation of NH3+ in the ground state X is considered.
