Abstract
A series of neutron-diffraction measurements for the single-crystal ice Ih (D2O) at different temperatures and pressure were carried out on PRISMA spectrometer using a He pressuriser at ISIS (U.K.). The measurements show no change in the diffraction pattern under the Bragg diffraction peaks for pressures up to 2.5 kbar at 130 K. When the pressure increases to 3.1 kbar at 120 K, the structure of ice Ih starts to deform, firstly the
