Abstract
A neutron quasi-elastic investigation on a well-orientated chain axis crystal of n-triacosane has been undertaken using the twin rotor spectrometer on the Pluto reactor at Harwell with an incident neutron wavelength of 2·64 Å. Data taken in the plastic phase show considerable quasi-elastic broadening, both perpendicular and parallel to the chain axis. Good agreement with experiment is obtained using a continuous rotation diffusion model with translational diffusion. On cooling below the plastic phase transition, slight quasi-elastic broadening isalso seen in both configurations.Keywords
