MULTIPLE-SCATTERING AND INELASTICITY CORRECTIONS IN THERMAL-NEUTRON SCATTERING EXPERIMENTS ON MOLECULAR-SYSTEMS

In this work we address the problem of multiple scattering and inelast icity corrections in neutron diffraction measurements for structural s tudies of molecular systems. A variety of pulsed neutron and reactor e xperiments was performed on hydrogenous samples under different experi mental conditions. Monte Carlo simulations were carried out on the bas is of a Synthetic Model to describe the neutron-molecule interaction, and they allowed a simultaneous evaluation of multiple, inelastic and beam attenuation processes into the samples. A very good agreement bet ween measurements and simulations was obtained in all cases, for our d emanding choice of samples and experimental conditions.
