We measured the energy dependence of the total reaction cross sections (sigma(R)) for the proton drip-line nucleus of neon isotopes, Ne-17, with a solid hydrogen target. The sigma(R) on a proton target in the low- and intermediate-energy regions were provided, where only a few values are available for unstable nuclei. The new data were compared with theoretical calculations using the Glauber model. In the low-energy region (similar to 100A MeV), the theoretical cross sections overestimate the experimental ones, whereas the theoretical ones significantly underestimate the experimental data in the intermediate energy region (similar to 300-500A MeV). We discuss several possibilities for solving this discrepancy. This work suggests the necessity of more careful investigations of the energy dependence of sigma(R) for various nuclei on a proton target to determine the nuclear size properties precisely.
