Notes:
Theoretical expressions are presented for the Fourier coefficients, derived in terms of a linear `ideal paracrystalline' lattice defined by Hosemann. These coefficients are related to the `coordination statistic' of paracrystallites and their size distribution. The expressions have been used to review earlier Fourier transform analyses on `Marlex 50' polyethylene and various heat-treated samples of petroleum coke and it has been established that these substances have a homogeneous paracrystalline disorder. Up-to-date results of the X-ray diffraction line-profile analyses of various paracrystalline substances are summarized and discussed.
