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.}, pages = {75--82}, title = {NEUTRON SCATTERING MEASUREMENTS ON VOSTOK ANTARCTIC ICE}, volume = {13}, year = {1999} }
