Off-specular scattering examples

Sample model

Off-specular scattering from a monodisperse distribution of long boxes.

  • The sample is made of very long boxes with length equal to $1000$ nm, width $20$ nm and height $10$ nm.
  • The particles are distributed along a one-dimensional lattice with a lattice spacing of $100$ nm in the $x$-direction.
  • The particles are rotated around the $z$-axis by $90^{\circ}$ so that their “infinite” dimension is parallel to the $y$-direction.

Real-space model

Measurement models

Example Offspec1 models an instrument that is scanning $\alpha_i$.

Example OffspecLambda models a time-of-flight neutron reflectometer that is scanning the incident wavelength $\lambda$.
