Abstract

The optical limit of the Glauber theory with zero-range approximation, which is successfully used at high energies to connect the nucleon density distribution with reaction cross-sections (σR), gives somewhat smaller values of σR by 10-20% at intermediate energies. We have precisely measured the σR for 12C on Be, C, and Al at 30A-200AMeV, and for 9Be on Be at 70A-100AMeV to investigate the enhancement of σR compared to the optical-limit calculation. From the enhancements, we deduced the nucleon-nucleon range as a function of energies. We deduced the density distribution of 8B analyzing the known experimental σR for 8B with an enhancement correction or with the finite range effect as a test.
