The reaction cross section (σR) for the neutron-rich nucleus 17B on a carbon target has been measured at an energy of 77A MeV by the transmission method. An enhancement of σR at intermediate energy compared to that at high energy was observed. The density distribution of 17B was deduced through the energy dependence of σR using a finite-range Glauber-type calculation under an optical-limit approximation as well as a few-body approach. The existence of a long neutron tail in 17B was demonstrated. The fraction of the wave function with the valence two-neutron configuration of (2s1/2) J=02 or (1d5/2)J=02 was found to be 50 ± 10% based on a finiterange few-body Glauber-type calculation.
