The Be-11(p, d)Be-10 reaction has been performed in inverse kinematics with a radioactive Be-11 beam of E/A = 35.3 MeV, Angular distributions for the 0(+) ground state, the 2(+), 3.37 MeV state and the multiplet of states around 6 MeV in Be-10 were measured at angles up to 16(cm)degrees by detecting the Be-10 in a dispersion-matched spectrometer and the coincident deuterons in a silicon array. Distorted wave and coupled-channels calculations have been performed to investigate the amount of 2(+) core excitation in Be-11(gs). The use of "realistic" Be-11 wave functions is emphasised and bound-state form factors have been obtained by solving the particle-vibration coupling equations. This calculation gives a dominant 2s component in the Be-11(gs) wave function with a 16% [2(+) x 1d] core excitation admixture. Cross sections calculated with these form factors are in good agreement with the present data. The Separation Energy prescription for the bound-state wave function also gives satisfactory fits to the data, but leads to a significantly larger [2(+) x 1d] component in Be-11(gs).
