The first exclusive breakup measurements for the nucleus Be-9 are presented. Breakup via several discrete states is observed following scattering off C-12 and Pb-208. The results support the prediction of a recent microscopic cluster calculation for a strong n+Be-8(2(+)) state component in the second excited state.
