Description
The average self-diffusion coefficients have been measured by neutron quasi-elastic scattering using the back-scattering techniques, in the smectic A, nematic and isotropic phases of TBBA. The results are compared with previous neutron and NMR results. We find that the agreement is good for the smectic A and isotropic phases only. We deduce that the NMR results are probably incorrect for the nematic phase. A simple model for self-diffusion in the smectic A and nematic phases which satisfactorily fits our results is also presented
