Abstract
We use microscopic wave functions defined in a multicluster model to compute +target scattering cross sections. The parameter sets describing are generated in the spirit of the stochastic variational method, and the optimal solution is obtained by superposing Slater determinants and by diagonalizing the Hamiltonian. The three-body continuum is approximated by square-integral wave functions. The microscopic wave functions are then used in a continuum-discretized coupled-channel (CDCC) calculation of and of elastic scattering. Without any parameter fitting, we obtain a fair agreement with experiment. For a heavy target, the influence of breakup is important, while it is weaker for light targets. This result confirms previous nonmicroscopic 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.
