N2 - Inelastic proton scattering exciting the 21/+ states in the neutron-rich beryllium isotopes 10,12Be has been studied in inverse kinematics. From a coupled-channel analysis, the deformation lengths for the 21/+ states in 12Be and 12Be were determined to be 1.80 ± 0.25 fm and 2.00 ± 0.23 fm respectively, indicating that a tendency towards strong quadrupole deformation is preserved for these nuclei and that the singly-closed shell structure does not prevail in 12Be. A quantitative analysis based on shell model calculations supports this picture. (C) 2000 Elsevier Science B.V.
