ABSTRACT:
The method for determining unknown structure of a solid by means of corpuscular beams or electromagnetic waves, includes the steps of radiating first incident waves to the solid to thereby obtain first scattering waves. radiating second incident waves to the solid in the direction opposite to the direction in which the first scattering waves had travelled, to thereby obtain second scattering waves, and measuring the intensity of the second scattering waves and the direction in which the second scattering waves had travelled.
