The diffuse scattering theory including correlation effects among thermal displacements of atoms is applied to background function in the Rietveld analysis. The oscillatory scheme of the diffuse scattering intensity from hexagonal VSe is explained by the correlation effects among far-neighboring Se-Se atoms. The values of the correlation effects depend on the interatomic distance and not on the crystal structure. The relation between correlation effects and force constants is discussed. © Akadémiai Kiadó, Budapest, Hungary 2009.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Correlation effect,Diffuse scattering,Force constants,Inter-atomic distances,Neutron diffraction measurements,Neutron scattering measurements,Thermal displacements,Thermal vibration[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Correlation effects,Diffuse scattering,Force constant,Neutron diffraction,Thermal vibration[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Acknowledgements The authors wish to express their thanks to Ibaraki University, Hitachi Ltd., and Ibaraki Prefecture for financial support in respect of their Collaborative Project.
