Abstract

Reaction cross sections (σ_R) and fragmentation cross sections (σ_F) of reactions of a ¹¹Be beam on C, Al targets were measured by a transmission method at 33A MeV. The σ_R have been determined to be 1.56±0.03 b for¹¹Be+¹²C, and 2.27±0.05 b for¹¹Be+²⁷Al. These values are extremely large compared with the systematics of stable nuclei. A large σ_F has also been observed for the ¹¹Be→¹⁰Be channel. Model calculations using present and 790A MeV data confirm the long neutron tail (neutron halo) in the ¹¹Be density distribution.
