Aa. Korsheninnikov et al., SPECTROSCOPY OF THE HALO NUCLEUS LI-11 BY AN EXPERIMENTAL-STUDY OF LI-11+P COLLISIONS, Physical review. C. Nuclear physics, 53(2), 1996, pp. 537-540
An experimental study of Li-11+p collisions at 75A MeV was performed.
The excited state of Li-11 at E = 1.25+/-0.15 MeV was observed, which
is a candidate for a neutron halo excitation. Four other Li-11 states
were manifested (at similar to 3.0, 4.9, 6.4, and 11.3 MeV). Angular
distributions were measured for elastic scattering Li-11+p and He-8+p.
Structure of the Li-11 halo was investigated using the eikonal approa
