Proton dynamics in supercritical water

摘要: An inelastic neutron scattering experiment has been performed on supercritical water at high momentum transfer, up to 90 A−1, in order study single proton dynamics. The value of the mean kinetic energy extracted framework impulse approximation. anisotropy distribution inside a molecule is discussed. experimental found good agreement with predictions harmonic model, under assumptions decoupling between translational, rotational and vibrational degrees freedom. Differences emerge our results those obtained recent sub- conditions. These differences are pointed out examined detail.
