differences are mainly due to non-unity detachment probability
and also (for larger energies) due to the idealisation of the barrier
in our simple model. We thus have seen that the overall shape of the
total AD cross section can be explained by a rather simple model.
On the other hand the details in the spectra and the weak
threshold structures in the total cross section curves are
sensitive to the details of the wave function for small $R$ where
the dynamics of the system is complicated and strongly nonlocal.
