Uncorrelated mixture of particles

Scattering from a mixture of cylinders and prisms without interference.

  • The sample comprises a substrate on which are deposited, in equal proportion, cylinders and prisms.
  • All particles are made of the same material.
  • Each type of particle has the same orientation.
  • The cylinders are $5$ nm high and $5$ nm in radius.
  • Each prism is $5$ nm high with an equilateral triangular base, whose side length is equal to $10$ nm.
  • There is no interference between the waves scattered by these particles. The distribution is therefore diluted.
  • The incident neutron beam is characterized by a wavelength of 0.1 nm.
  • The incident angles are $\alpha_i = 0.2 ^{\circ}$ and $\varphi_i = 0^{\circ}$.
  • The simulation is performed using the Distorted Wave Born Approximation (due to the presence of a substrate).
