摘要：

The energy level splitting due to tunnelling motion of the methyl groups in sodium acetate trihydrate, Na(CH3COO)3H2O, has been measured by inelastic neutron scattering at 4K for hydrostatic pressures up to 5 kbar. The splitting falls from 5.7 mu eV at atmospheric pressure to 2.2 mu eV at 5 kbar with an exponential pressure dependence indicating a linear dependence of the height of the hindering potential on pressure.
