Abstract

Interaction cross sections (σ₁) and transverse momentum P_t distributions of ⁹Li fragments in ¹¹Li reactions were measured 1467 using p and d targets at 800A MeV, and Be and C targets at 400A MeV. The density distribution of the ¹¹Li nucleus has been determined for the first time from these σ_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 ⁹Li 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.
