Role of the total isospin 3/2 component in three-nucleon reactions [PDF]
, 2016 We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential

Neutron Scattering off One-Neutron Halo Nuclei in Halo Effective Field Theory [PDF]
arXiv, 2023 Neutron scattering off neutron halos can provide important information about the internal structure of nuclei close to the neutron drip line. In this work, we use halo effective field theory to study the $s$-wave scattering of a neutron and the spin-parity $J^P=\frac{1}{2}^+$ one-neutron halo nuclei $^{11}\rm Be$, $^{15}\rm C$, and $^{19}\rm C$ at ...
arxiv
, 2002 The technique of polarized neutron scattering is reviewed with emphasis on applications. Many examples of the usefulness of the method in various fields of physics are given like the determination of spin density maps, measurement of complex magnetic structures with spherical neutron polarimetry, inelastic neutron scattering and separation of coherent ...

Understanding the Role of Hydrogen and Oxygen in Electronic Phase Changes of Nickelates
Advanced Functional Materials, EarlyView.The reversible exchange of hydrogen and oxygen in solids is key to their electronic and electro‐chemical functionality. A combination of methods is employed to study the interaction of hydrogen with a prototypical quantum material in a non‐destructive and time‐dependent manner.

Superchaotropic Nano‐ion Binding as a Gelation Motif in Cellulose Ether Solutions
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 Nano‐ions, like polyoxometalates and boron clusters, co‐assemble strongly with non‐ionic solutes in water driven by the chaotropic effect. Here, nano‐ion assembly with non‐ionic cellulose ethers (CE) is shown to result in unprecedented thickening effects and gelation of CE‐solutions. An interplay of electrostatic repulsion and attraction between chains

Interaction of Ultra-Cold Neutrons with Condensed Matter [PDF]
Nucl.Instrum.Meth.A440:704-708,2000, 1999 General theory of neutron scattering (elastic and inelastic) is presented. It is applicable for the whole domain of slow neutrons and includes as limiting cases existing theories for thermal and cold neutrons and for elastic scattering of UCN. New expression for inelastic scattering cross section for UCN is proposed. It differs from the usually used by
