  The full quantum mechanical (QM) model of inclusive breakup of
Ichimura-Austern-Vincent (IAV) is implemented in this paper to calculate
breakup from heavy radioactive nuclei on a $^9$Be target at intermediate
energies. So far it had been implemented and applied only to low energy
reactions with light projectiles. The IAV model is successful in predicting
absolute cross sections among other observables. In order to get insight on the
content of the model in the case of the complicated heavy-ion reactions,
results are compared with those of the semiclassical transfer to the continuum
(TC) model. Because the TC is based on analytical formulae the dynamics of the
breakup as it is contained in the rather involved IAV formalism will become
more transparent. Heavy-ion reactions at high energies ($>$50A.MeV) are
demanding from the computational point of view because of the high number of
partial waves involved, typically around 100. The TC constitutes a useful
alternative to the full QM calculations whenever predictions and/or estimates
are necessary. It allows also for a systematic, fast evaluation of breakup
observables. In the applications of both methods we use state-of-the art
optical potentials and structure information. Excellent agreement is found
between the calculated results of both methods and with available experimental
data which shows that the qualitative and quantitative understanding of most
aspects of one nucleon breakup is well under control.
