Inelastic Neutron Scattering Selection Rules

Neutron scattering Selection Rules
This program calculates systematic absences in inelastic neutron scattering spectra, due to the phonon symetry.

Input data :
  1. Space group number as given in ITA.
  2. k-vector data :
    • Reciprocal lattice basis type, which may be primitive (as in Cracknell, Davies, Miller & Love tables) or dual to the conventional (ITA).
    • k-vector coordinates relative to chosen basis as any three decimal numbers or fractions.
    • Label of the k-vector (up to three letters).

  3. You may change the conventional basis of the group to another one by entering a transformation that relates two bases. The transformation, in general, consists of a linear part and an origin shift.
