Proton mean kinetic energy in supercritical water was determined using deep inelastic neutron scattering (DINS) technique to validate harmonic approximation and the hypothesis of decoupling among translational, rotational and vibrational degrees of freedom. Anisotropy of proton momentum distribution due to nonspherical molecular symmetry in water was also assessed. Proton mean kinetic energy was well described by a semi-classical harmonic model. The experimental results were found to be in good agreement with the theoretical predictions.

Abstract
Proton mean kinetic energy in supercritical water was determined using deep inelastic neutron scattering (DINS) technique to validate harmonic approximation and the hypothesis of decoupling among translational, rotational and vibrational degrees of freedom. Anisotropy of proton momentum distribution due to nonspherical molecular symmetry in water was also assessed. Proton mean kinetic energy was well described by a semi-classical harmonic model. The experimental results were found to be in good agreement with the theoretical predictions.| File | Dimensione | Formato | |
