The magnetic resonance at 41 meV observed in neutron scattering studies of YBa2Cu3O7 holds a key position in the understanding of high-T-c, superconductivity. Within the SO(5) model for superconductivity and antiferromagnetism, we have calculated the effec ...
As a conclusion, one can say that the main goal of this report was reached: spin wave dispersion was calculated for Nd2Fe14B crystal samples which were also prepared for neutron scattering experiment. Indeed, several steps were made in order to perform suc ...
Using a first-principles approach, we study the vibrational properties of vitreous SiO2 which are measured in neutron-scattering experiments. We adopt a model structure consisting of corner-sharing tetrahedra, which was previously generated using first-pri ...
Small angle neutron scattering experiments have been undertaken on the tempered martensitic steel EUROFER97 after proton irradiation at 250 and 350 degreesC and for doses of 0.3 and 1 dpa. It has been qualitatively shown that the scattering arises from dis ...
The angular distributions of the differential cross-sections for scattering of 14.1 MeV neutrons to the Q = 0, – 1.74, – 2.15, – 3.58, – 4.77, – (5.11 + 5.16 + 5.18), – (5.92 + 6.04 + 6.13), – 6.56 and – (6.88 + 7.0) MeV levels of 10B have been measured fo ...
The 12C(n, n), (n, n') and (n, n') 3 α reactions have been studied at 14.1 MeV by a time-of-flight method, with a scintillating scatterer. The angular distributions and integrated cross sections were obtained for the following channels: Q = 0 (0+) and -4.4 ...
CuGeO3 is a good realization of a spin-Peierls system. Using neutron scattering, we have investigated the transition from the dimerized spin-Peierls phase to an incommensurately modulated high-field phase. The incommensurate period has been measured for fi ...
This report describes the aqueous solution self-assembly of a series of polystyrenem-b-poly(L-lysine)n block copolymers (m = 8-10; n = 10-70). The polymers are prepared by ring-opening polymerization of e-benzyloxycarbonyl-L-lysine AT-carboxyanhydride usin ...
