Abstract

The electromagnetic dissociation (EMD) cross sections of light neutron-dripline projectile ¹¹Li have been inferred from the target dependence of the interaction cross section, σ₁, and the two-neutron-removal cross section, σ_-2n, at an incident energy of 0.8 GeV/nucleon. The EMD cross sections of ¹¹Li projectiles on a lead target were found to be quite large; σ_I^EMD(¹¹Li+Pb)=1.72 ±0.65b and σ_-2n^EMD(¹¹Li+Pb)=0.89 ±0.10b, which are approximately 80 times larger than those of ¹²C projectiles after scaling the cross section by Z_proj². The large EMD cross section is related to the possible existence of a soft mode of the giant dipole resonance at low excitation energy in the extremely neutron-rich nuclei.
