Abstract

Data have been obtained on exclusive single neutron knockout cross sections from ¹²Be to study its ground state structure. Preliminary cross sections for the first (0.32 MeV, 1/2^-) and second (1.78 MeV, 5/2⁺, unbound) excited states in ¹¹Be have been obtained, giving evidence of significant admixtures of both ν(1p_1/2) ² and ν(1d_5/2)² configurations in the ground state of ¹²Be.
