Differential cross sections for elastic scattering of neutrons from ²⁰⁸Pb target have been calculated with TALYS 1.6 nuclear code. Angular distributions were obtained for incident neutron energies of 5 to 96 MeV. The calculated data were compared with experimental results from literature. Calculations for angular distribution of elastic scattering of ²⁰⁸Pb, made with TALYS 1.6 nuclear code, show good agreement with experimental data.

In this paper studies of neutron diffraction properties of the double crystal (+n,-m) setting of a bent perfect crystal Si(311) in the fully asymmetric diffraction geometry with the output beam compression and the bent perfect crystal Si(220) in a symmetric diffraction geometry, are presented. The properties of the (+n,-m) setting were studied for different curvatures of the individual crystal slabs. It has been found that after a beam condensation this fully asymmetric diffraction geometry can provide a monochromatic beam of a small width and of a practical use.

Neutrons and X-rays are well established tools for studying properties of condensed matter. With the advent of synchrotron radiation facilities their high photon fluxes started to be effectively used in the fields reserved earlier for neutrons. Although the two techniques are conceptually so similar that many physical problems can be solved using either technique, there are apparent fields in which one method is superior with respect to the other one. Therefore both techniques are often needed for characterization of the material of interest. The paper concentrates on the studies of some static properties of metals and alloys. Relatively wide range of phenomena is presented, starting from structural aspects and ending on the sophisticated studies of the magnetic moment components. The paper is intended to bring a short (yet necessarily subjective and incomplete) review of what has recently been achieved by using neutrons and X-rays in metal (or more precisely - metallic states) studies.

We report on low temperature magnetic properties of KEr(MoO_4)_2 single crystal, which was investigated from 0.28 K to 30 K in magnetic fields up to 6.5 T. Neutron elastic data collected above and below transition temperature T_{N} ≈ 0.95 K suggest that an antiferromagnetic ordering establishes at low temperatures. The magnetic model within the A_{x}C_{z} mode assuming only magnetic moment at erbium atom positions is suggested. Synchrotron experiment in moderate magnetic fields at temperatures above T_{N} explains the origin of observed signal(s) at (0K0) reflection positions, K odd.

We present magnetic and structural properties of Ln[Fe(CN)_6]·xH_2O, Ln = Pr, La single crystals investigated by means of elastic neutron diffraction and heat capacity down to 0.03 K and susceptibility and magnetization measurements. The susceptibility data were taken on the commercial SQUID magnetometer (Quantum Design) in the range between 2 K and 30 K and in fields up to 5 T. Our low temperature neutron diffraction data taken in a zero field rules out some of antiferromagnetic models suggested in the literature.
