摘要：

The charge and mass deformation parameters of the neutron-rich isotopes Mg-30,Mg-32 have been extracted from inelastic scattering at 32A MeV on Pb-208 and C-12 targets. The measured inelastic cross sections for the first 2(+) states were compared to coupled-channels calculations, which take into account the feeding from higher excited states. In the framework of the rotational model the charge and mass deformations are identical and large (\ beta \ similar to 0.5 - 0.6) for both isotopes.
