We present an experimental investigation of the hydrogen nuclear momentum distribution in biphenyl using deep inelastic neutron scattering. Our experimental results suggest that the local potential affecting hydrogen is both harmonic and isotropic wi

In this work, an investigation of supercritical water is presented combining inelastic and deep inelastic neutron scattering experiments and molecular dynamics simulations based on a machine-learned potential of ab initio quality. The local hydrogen

The experimental thermal neutron cross sections of the 20 proteinogenic amino acids have been measured over the incident-neutron energy range spanning from 1 meV to 10 keV and data have been interpreted using the multi-phonon expansion based on first
This study presents the first direct and quantitative measurements of the nuclear momentum distribution anisotropy and the quantum kinetic energy tensor in stable and metastable (supercooled) water near its triple point using Deep Inelastic Neutron S

We present here a study of the dynamics of two monomeric proteins, trypsin and lysozyme, by means of elastic and quasielastic neutron scattering under medium-to-high pressure conditions (1-1200 bar). The internal motions as probed from the average pr

For the first time inelastic neutron scattering measurements on a poly-crystalline sample of D2O up to the O-D stretching region are presented. The data have been analysed, treating the coherent scattering contribution within the incoherent approxima
