Override a structure's scattering lengths¶

On Structure → Extra, expand Scattering lengths. An empty list uses the built-in table. To override it, choose Append a scattering length, enter the atom type and its coherent scattering length in femtometres. Remove a row to use the built-in value again.

Use an override when the atom type needs a value specific to your sample. See neutron scattering and structure factors.
