The pair distribution function and structure factor of spherical particles
نویسندگان
چکیده
An envelope function is derived which multiplies the pair distribution function (PDF) of an infinite solid to obtain that of a spherical particle with the same crystal structure. Distributions of particle sizes are then considered, and the analytical results are used to predict the distribution from a PDF obtained experimentally. The peak broadening for the associated structure factor, expressed as a convolution function, is calculated exactly for the distribution of particle sizes considered.
