neutronpy.energy.Energy

class neutronpy.energy.Energy(energy=None, wavelength=None, velocity=None, wavevector=None, temperature=None, frequency=None)[source]

Class containing the most commonly used properties of a neutron beam given some initial input, e.g. energy, wavelength, velocity, wavevector, temperature, or frequency. At least one input must be supplied.

Parameters:
energy : float

Neutron energy in millielectron volts (meV)

wavelength : float

Neutron wavelength in angstroms (Å)

velocity : float

Neutron velocity in meters per second (m/s)

wavevector : float

Neutron wavevector k in inverse angstroms (1/Å)

temperature : float

Neutron temperature in kelvin (K)

frequency : float

Neutron frequency in terahertz (THz)
Returns:
Energy object
