Abstract
The structure of 6He is explored with proton elastic and inelastic scattering to the first 2+ excited state (Q = -1.8 MeV) of 6He in the inverse kinematics using a 24.5 A MeV 6He beam. The distorted wave approximation (DWA) with an optical potential obtained by folding an effective nucleon-nucleon (NN) g-matrix with the 6He 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 6He has an extended (halo) neutron matter distribution. © 2002 Elsevier Science B.V. All rights reserved.
