✦ Synopsis

The 11 Be(p, d) 10 Be reaction has been performed in inverse kinematics with a radioactive 11 Be 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 10 Be were measured at angles up to 16 • cm by detecting the 10 Be 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 11 Be gs . The use of "realistic" 11 Be 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 11 Be gs wave function with a 16% [2 + ⊗ 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 + ⊗ 1d] component in 11 Be gs .
