Abstract
Energy distributions of neutrons scattered incoherently from nematic MBBA have been recorded. Measurements for various scattering angles and for two geometries (neutron momentum transfer parallel and perpendicular to the nematic director) have been made. The results have been interpreted as giving evidence of rotational proton jumps, whose correlation times are of the order of 10-12 s.
