METHOD FOR DETERMINING STRUCTURE OF SOFT MATERIAL

摘要

A method for determining the three-dimensional structure of a low-density material called a soft material not ordered on an atomic scale but ordered o n a mesoscale (20 to 500 angstroms), especially by means of a high-resolution transmission microscope. A soft material is imaged by means of a transmissio n microscope in three or more directions meaningful in crystallography. The image is Fourier-transformed to calculate the amplitude and phase of the crystal structure factor. Fourier inverse transform using the values is carried out and hence a space group of the soft material is determined.
