Gamma ray production in inelastic scattering of neutrons produced by cosmic muons in $^{56}$Fe [PDF]
, 2010 We report on the study of the intensities of several gamma lines emitted after the inelastic scattering of neutrons in $^{56}$Fe. Neutrons were produced by cosmic muons passing the 20t massive iron cube placed at the Earth's surface and used as a passive shield for the HPGe detector.

Moisture‐Dependent Vibrational Dynamics and Phonon Transport in Nanocellulose Materials
Advanced Materials, EarlyView.Uptake of water in cellulose play an important role in modulating the structure and phonon transport. This study reports how moisture‐dependent structural modification relates to the vibrational dynamics and phonon transport and scattering of nanocellulose using inelastic neutron scattering and wide angle X‐ray scattering.

Rejection-based sampling of inelastic neutron scattering [PDF]
, 2018 Distributions of inelastically scattered neutrons can be quantum dynamically described by a scattering kernel. We present an accurate and computationally efficient rejection method for sampling a given scattering kernel of any isotropic material. The proposed method produces continuous neutron energy and angular distributions, typically using just a ...

Advanced Materials, EarlyView.Liquid‐phase transmission electron microscopy enables visualization of nanoscale processes involving liquid media. Yet, it suffers from beam effects, such as radiolysis of the liquid, sample heating, and membrane charging. This review summarizes beam effect fundamentals, describes modeling and assessment, and illustrates handling strategies.

Measurement of Leading Neutron Production in Deep-Inelastic Scattering at HERA [PDF]
Eur.Phys.J.C68:381-399,2010, 2010 The production of leading neutrons, where the neutron carries a large fraction x_L of the incoming proton's longitudinal momentum, is studied in deep-inelastic positron-proton scattering at HERA. The data were taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 122 pb^{-1}.

Sequential Structural Evolution Triggered by O─O Dimerization in Oxygen‐Redox Reactions
Advanced Energy Materials, EarlyView.This study reveals the origin of electrode degradation in oxygen‐redox reactions as sequential structural evolution. Contrary to the widely accepted belief, transition‐metal migration is not induced before the dimerization of unstable oxidized oxide ions in the deeply charged states.

Long-range order and low-energy magnetic excitations in CeRu2Al10
, 2010 The nature of the unconventional ordered phase occurring in CeRu2Al10 below T0 = 27 K was investigated by neutron scattering. Powder diffraction patterns show clear superstructure peaks corresponding to forbidden (h + k)-odd reflections of the Cmcm space
