摘要：

The structure of He-6 is explored with proton elastic and inelastic scattering to the first 2(+) excited state (Q = -1.8 MeV) of He-6 in the inverse kinematics using a 24.5 A MeV He-6 beam. The distorted wave approximation (DWA) with an optical potential obtained by folding an effective nucleon-nucleon (NN) g-matrix with the He-6 density matrix elements as given by a large basis shell model is used to analyse the data. The comparison of predictions with the data confirms the view that He-6 has an extended (halo) neutron matter distribution. (C) 2002 Elsevier Science B.V. All rights reserved.
