Abstract : The scattering patterns are calculated from anisotropic rods having an arbitrary orientation of the principal polarizability axis with respect to the rod axis. The effect of a distribution of orientation of the rods is explored, leading to a change in scattering patterns produced by orienting the rods upon stretching the sample. Scattering patterns are affected by the relationship between the refractive indices of the rods and that of the surroundings. The influence of the optic axis orientation angle changing upon orienting the rods is explored. Theoretical patterns are compared with experimental ones obtained upon stretching polytetrafluorethylene (PTFE) films. (Author)
