We measured the incoherent inelastic neutron scattering (IINS) of Vostok Antarctic ice in order to investigate the arrangement of protons in the ice and to verify the proton ordering in Antarctic ice previously observed by IINS measurements on Dome Fuji Antarctic ice (FUKAZAWA et al., Chem. Phys. Lett., 294,554,1998a). The IINS spectrum of Vostok ice at 500m in depth has a peak at 19 meV in the region of translational lattice vibrations, while the peak in Vostok ice at 2452m in depth is much lower. Ice XI with a proton-ordered arrangement has a sharp peak at 19meV, while ordinary ice (ice Ih) with a proton-disordered arrangement does not have such a peak. These results of analysis of the IINS spectra indicate that Vostok ice at 500m in depth has a proton-ordered arrangement.
