Uranium-238 is used extensively in nuclear reactor cores. Its nuclear properties have a significant effect on many aspects of the entire fuel cycle process from enrichment facilities and power production to nuclear waste storage facilities. In order to safely design such systems, an accurate evaluation of neutron interactions with U is required. This paper describes a process of quantifying dif...

Advanced modelling of neutron induced reactions on 238U nucleus is aimed at improving our knowledge of the neutron scattering. Capture and fission channels are well constrained by available experimental data and neutron standard evaluation. A focus of this contribution is on elastic and inelastic scattering cross sections. The employed nuclear reaction model includes – a new rotational-vibratio...

Results of simultaneous thermal analysis (STA), synchrotron powder diffraction (in the range 300–973 K) and inelastic neutron scattering (at 285 and 505 K) on non-superionic βand superionic α-AgCuSe are reported. The sample is stable in argon on heating. The volume change at the superionic phase transition is about 5%. A model for the average structure of α-AgCuSe is proposed. No anomalies in t...

We have studied the amino acid L-leucine (LEU) using inelastic neutron scattering, X-rays and neutron diffraction, calorimetry and Raman scattering as a function of temperature, focusing on the relationship between the local dynamics of the NH(3), CH(3), CH(2) and CO(2) moieties and the molecular structure of LEU. Calorimetric and diffraction data evidenced two novel phase transitions at about ...

Single-molecule magnets (SMMs) based on lanthanide ions display the largest known blocking temperatures and are the best candidates for molecular magnetic devices. Understanding their physical properties is a paramount task for the further development of the field. In particular, for the poly-nuclear variety of lanthanide SMMs, a proper understanding of the magnetic exchange interaction is cruc...

Recent computer simulation studies contain sufficient information about the atomic disorder and motion to allow a calctlation of the dynamical response of superionic crystals and melts which may be compared with measurements of inelastic neutron scattering and Raman scattering. The high frequency part of this response is essentially that of anharmonic vibrations in a disorderd lattice. The low ...

An overview is given of some recent and planned experiments which have or will substantially increase our knowledge of the electromagnetic properties of the few body systems. Specific examples include the proton and neutron elastic form factors, the deuteron elastic form factors, deuteron threshold electro-disintigration and quasi-elastic scattering, deuteron photodisintigration, and finally me...
