摘要:
We report on neutron-diffraction measurements of liquid benzene under standard thermodynamic conditions. The measurements are taken at two different incident neutron wavelengths to cover an extendedQrange. The diffraction data are normalized and inelastic effects corrected, considering only the total sample scattering cross-section. To determine the molecular structure from the diffraction data, we have to introduce direction-dependent meansquare displacements for the carbon and deuterium atoms. An analysis is made of the pair distribution function in terms of a first-shell solid-like structure, and good agreement is found with previous x-ray measurements.
