Inelastic neutron scattering evidence for anomalous H-H distances in metal hydrides. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Hydrogen in metals alters the electronic structure of such materials and hence modifies the physical and chemical properties. In conventional transition metal hydrides containing atomic hydrogen, the minimum hydrogen–hydrogen distances are ...

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

Multiple Scattering Theory for Slow Neutrons (from thermal to ultracold) [PDF]
, 1999 The general theory of neutron scattering is presented, valid for the whole domain of slow neutrons from thermal to ultracold. Particular attention is given to multiple scattering which is the dominant process for ultracold neutrons (UCN). For thermal and cold neutrons, when the multiple scattering in the target can be neglected, the cross section is ...

Quasi-elastic neutron scattering in the high-field phase of a Haldane antiferromagnet [PDF]
, 2001 Inelastic neutron scattering experiments on the Haldane-gap quantum antiferromagnet NDMAP are performed in magnetic fields below and above the critical field Hc at which the gap closes. Quasi-elastic neutron scattering is found for H>Hc indicating topological excitations in the high field phase.

Inelastic neutron scattering peak in Zn substituted YBa2Cu3O7 [PDF]
, 1999 The effects of nonmagnetic impurities on the neutron scattering intensity are studied for a model of the copper oxide layers in the normal state. The contribution to the Q=(pi,pi) neutron scattering intensity from processes involving the scattering of the spin fluctuations from an impurity with large momentum transfers are calculated within the random ...
