get_holz_angle#

diffsims.utils.sim_utils.get_holz_angle(electron_wavelength, lattice_parameter)[source]#

Converts electron wavelength and lattice paramater to holz angle Parameters ———- electron_wavelength : scalar

In nanometers

lattice_parameterscalar: In nanometers

Returns:

scattering_anglescalar: Scattering angle in radians

Examples

>>> import diffsims.utils.sim_utils as sim_utils
>>> lattice_size = 0.3905 # STO-(001) in nm
>>> wavelength = 2.51/1000 # Electron wavelength for 200 kV
>>> angle = sim_utils.get_holz_angle(wavelength, lattice_size)
