  We use microscopic 9Be wave functions defined in a alpha+alpha+n multicluster
model to compute 9Be+target scattering cross sections. The parameter sets
describing 9Be are generated in the spirit of the Stochastic Variational Method
(SVM), and the optimal solution is obtained by superposing Slater determinants
and by diagonalizing the Hamiltonian. The 9Be three-body continuum is
approximated by square-integral wave functions. The 9Be microscopic wave
functions are then used in a Continuum Discretized Coupled Channel (CDCC)
calculation of 9Be+208Pb and of 9Be+27Al elastic scattering. Without any
parameter fitting, we obtain a fair agreement with experiment. For a heavy
target, the influence of 9Be breakup is important, while it is weaker for light
targets. This result confirms previous non-microscopic CDCC calculations. One
of the main advantages of the microscopic CDCC is that it is based on
nucleon-target interactions only; there is no adjustable parameter. The present
work represents a first step towards more ambitious calculations involving
heavier Be isotopes.
