Icosahedron

A regular icosahedron.

Constructor

Icosahedron(a)

Parameters:

  • a, length of the edge

Usage

As for any other Form factor.

Implementation

Class Icosahedron inherits from the interface class IFormfactor.

Form factor computation is based on the generic form factor of a polyhedron with inversion symmetry provided by libformfactor .

Volume has been validated against $$ V= \dfrac{5}{12}(3+\sqrt{5})a^3 \approx 2.182 \space a^3. $$

Example

Scattering by uncorrelated, oriented truncated icosahedra for horizontal incidence:
