SCATTERING OF RADIOACTIVE NUCLEI HE-6 AND H-3 BY PROTONS - EFFECTS OF NEUTRON SKIN AND HALO IN HE-6, HE-8, AND LI-11

摘要

In an experimental study of He-6+p and H-3+p collisions at similar to 70 A MeV, the elastic scattering angular distributions were measured and the known excited state He-6(1.8)* was observed. Comparative analysis of existing experimental data on proton elastic scattering by He-4, He-6, Li-6, He-8, Li-9, and Li-11 was performed. Effects of valence neutrons were investigated using the eikonal approach. A difference between Li-11 and He-6,He-8 was found. (C) 1997 Elsevier Science B.V. [References: 34]
