Scattering#
The scattering module contains additional general functions for calculating diffuse scattering patterns.
- form(ions, Q, source='x-ray')[source]#
Scattering form factor \(f(Q)\).
- Parameters:
- ions1d array, str
Ions.
- Q1d array
Magnitude of wavevector.
- sourcestr, optional
Radiation source. Either
'x-ray'or'electron'. Defualt issource='x-ray'.
- Returns:
- f1d array
Has the same shape as the input wavevector.
- length(atms, n_hkl)[source]#
Scattering length \(b\) of neutrons.
- Parameters:
- atms1d array, str
Atoms or isotopes.
- n_hklint
Number of reciprocal space points.
- Returns:
- b1d array
Has the shape as the number of reciprocal space points.
- phase(Qx, Qy, Qz, rx, ry, rz)[source]#
Phase factor \(e^{i\boldsymbol{Q}\cdot\boldsymbol{r}}\).
- Parameters:
- rx, ry, rz1d array
Components of spatial vector in Cartesian coordinates.
- Qx, Qy, Qz1d array
Components of wavevector in Cartesian coordinates.
- Returns:
- factor1d array
Has the same shape as the input wavevector and spatial vector components.
