get_holz_angle#

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

Converts electron wavelength and lattice paramater to holz angle :param electron_wavelength: In nanometers :type electron_wavelength: scalar :param lattice_parameter: In nanometers :type lattice_parameter: scalar

Returns:: scattering_angle – Scattering angle in radians
Return type:: scalar

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)
