摘要：

Interaction cross sections (sigma(I)) and transverse momentum P(t) distributions of Li-9 fragments in Li-11 reactions were measured using p and d targets at 800A MeV, and Be and C targets at 400.4 MeV. The density distribution of the Li-11 nucleus has been determined for the first time from these sigma(I)'s. It is confirmed that only a distribution with a long tail (halo) consistently reproduces the observed data. From a combined analysis of P(t) distributions of Li-9 and of neutrons, the momentum correlation of the two halo neutrons was extracted. It suggests that these neutrons have a strong tendency to move in the same direction.
