“…The constants a and b appearing in the threshold law (23) (Macek and Ihra 1997;Ihra et al . 1997a) were derived on the basis of an Airy function for the hyperangle motion, as this is the ground state wave function in the binding (for negative R) linear potential derived from (18) and the lower line of (20).…”

“…The theory of Macek and Ovchinnikov was applied to the s-wave model by Macek and Ihra (1997) and by Ihra et al . (1997a), and it predicts an exponential supression of the quantum mechanical ionisation cross section as E → 0 for fixed E b .…”

Electron impact ionisation of one-electron atoms or ions is well described in the near threshold region by Wannier’s theory based on estimating the classical phase space available to two outgoing electrons in the Coulomb field of the residual ion. The relation between classical dynamics and quantum mechanics in the near threshold region becomes more complicated and interesting in ‘non-Wannier situations’, where classical ionisation is either strictly forbidden or strongly inhibited. This paper focusses on two examples of such situations, which have been receiving increasing attention in recent years, namely the s-wave model and the case where the exponent in Wannier"s law diverges.
