Neutron structure function $F_2^n(x)$ from deep inelastic electron scattering off few-nucleon systems [PDF]

Phys.Rev. C64 (2001) 055203, 2001
The possibility of a reliable extraction of the neutron deep inelastic structure function, $F_2^n(x)$, for $ x < 0.85$ from joint measurements of deep inelastic structure functions of deuteron, $^{3}He$ and $^{3}H$ is investigated. The model dependence in this extraction, linked to the possible different interactions between nucleons in nuclei, is ...

Neutron-driven collectivity in light tin isotopes: Proton inelastic scattering from 104Sn

Physics Letters B, 2015
Inelastic scattering cross sections to individual bound excited states of 104Sn were measured at 150 MeV/u beam energy and analyzed to evaluate the contribution of neutron and proton collectivity.

Inelastic neutron scattering applied to the investigation of collective excitations in topologically disordered matter

Condensed Matter Physics, 2008
Inelastic neutron scattering techniques are introduced here as one of the most important experimental techniques in the investigation of collective excitations in fluids (liquids and compressed gases) and amorphous solids.

Neutron spin echo spectroscopy with a moving sample

Scientific Reports, 2023
Neutron spin echo spectroscopy is a high resolution inelastic neutron scattering method probing nanosecond dynamics. It is well suited to study the atomistic motion in polymer systems and contributes to our understanding of viscoelasticity.

Inelastic neutron and x-ray scattering as probes of the sign structure of the Fe-pnictide superconducting gap [PDF]

Phys. Rev. B 83, 220505(R) (2011), 2011
Neutron spin-flip scattering observations of a resonance in the superconducting state is often taken as evidence of an unconventional superconducting state in which the gap changes sign $\Delta(k+Q)=-\Delta(k)$ for momentum transfers $Q$ which play an important role in the pairing.

Single Atom Sites in Ga‐Ni Supported Catalytically Active Liquid Metal Solutions (SCALMS) for Selective Ethylene Oligomerization

ChemPhysChem, EarlyView.
Supported catalytically active liquid metal solutions (SCALMS) based on liquid gallium‐nickel (Ga−Ni) alloys have demonstrated high catalytic activity and stability in the selective oligomerization of ethylene. In this study of novel Ga−Ni SCALMS, catalytic, spectroscopic, microscopic, and computational methods provide a unique and first insight into ...

Towards understanding the magnetic properties of the breathing pyrochlore compound Ba3Yb2Zn5O11through single-crystal studies

npj Quantum Materials, 2022
Ba3Yb2Zn5O11 is exceptional among breathing pyrochlore compounds for being in the nearly-decoupled limit where inter-tetrahedron interactions are weak, hosting isolated clusters or molecular magnet-like tetrahedra of magnetic ytterbium (Yb3+) ions.

Folding model analysis of elastic and inelastic proton scattering on Sulfur isotopes [PDF]

Nucl.Phys. A706 (2002) 61-84, 2002
The folding formalism for the nucleon-nucleus optical potential and inelastic form factor is applied to study elastic and inelastic proton scattering on 30-40S isotopes. A recently developed realistic density dependent M3Y interaction, well tested in the folding analysis of nucleus-nucleus elastic and inelastic scattering, is used as effective NN ...

Detection of an internal density change in an anthropomorphic head phantom via tracking of charged nuclear fragments in carbon‐ion radiotherapy

Medical Physics, EarlyView.
Abstract Background Carbon‐ion radiotherapy provides steep dose gradients that allow the simultaneous application of high tumor doses as well as the sparing of healthy tissue and radio‐sensitive organs. However, even small anatomical changes may have a severe impact on the dose distribution because of the finite range of ion beams.
