Reaction cross sections (sigma(R)) for the proton drip-line nucleus Ne-17 have been measured on Be-9, C-12, and Al-27 targets at 64 and 42 MeV/nucleon by the transmission method. From the energy dependence of the sigma(R) including the high energy data, the density distribution of Ne-17 was deduced through a modified Glauber-type calculation. It is indicated that Ne-17 has a long tail in the density, consistent with a (2s(1/2))(2)-dominant configuration of two valence protons.
