FuzzySphere

A sphere with a fuzzy surface.

Constructor

FuzzySphere(R, sigma)

Parameters:

  • R, mean radius.
  • sigma, fuzziness length.

Usage

As for any other Form factor.

Implementation

Class FuzzySphere inherits from the interface class IFormfactor .

The form factor is computed as $$F(q)=F_{\rm sphere}(q) \exp(-\sigma^2 q^2 /2)$$ where $F_{\rm sphere}(q)$ is the form factor of a hard sphere.

History

Previously named “SphereGaussianRadius”. In BornAgain 1.20 renamed and simplified to match the fuzzy_sphere model of SasView.

The SasView manual gives credit to M Stieger, J. S Pedersen, P Lindner, W Richtering, Langmuir 20, 7283-7292 (2004).
