Even at room temperature, quantum mechanics plays a major role in determining the
quantitative behavior of light nuclei, changing significantly the values of physical properties …

Deep inelastic neutron scattering measurements from orthorhombic ordered HCl are
presented and analyzed in order to clarify the problem of an anomalous deficit in the neutron …

Application of neutron Compton scattering, which operates in the attosecond time scale, to
(a) the equimolar H 2-D 2 mixture and (b) the mixed-isotope system HD (liquids, both at 20 …

We studied the effective temperatures of hydrogen and carbon in solid ethane at 80 K and
triphenylmethane at 22 K at the VESUVIO spectrometer (ISIS Neutron and Muon Source …

We investigated the neutron cross sections of hydrogen and deuterium by means of the
deep inelastic neutron-scattering technique in H 2 OD 2 O mixtures. The interest in this work …

We have devised a simple and practical method for the extraction of single-particle mean
kinetic energy from the Helmholtz free energy, when this quantity is known for a pair of …

The present work shows a series of results of Deep Inelastic Neutron Scattering (DINS)
experiments on light and heavy water mixtures performed at the spectrometer VESUVIO …

A shortfall of the scattering intensity from protons has been observed in liquids (water,
benzene, etc.) and solids (metal hydrogen systems, organic polymers, etc.) using neutron …

We describe the procedure to determine effective temperatures employing the data collected
by the detectors of the VESUVIO spectrometer (ISIS pulsed neutron source), employing the …
