const string & ObjCryst::ScatteringPowerAtom::GetClassName ( ) const

Name for this class ("RefinableObj", "Crystal",...).

This is only useful to distinguish different classes when picking up objects from the RefinableObj Global Registry

Definition at line 323 of file ScatteringPower.cpp.

string ObjCryst::ScatteringPowerAtom::GetElementName ( ) const

REAL ObjCryst::ScatteringPowerAtom::GetForwardScatteringFactor ( const RadiationType ) const

virtual

Get the scattering factor at (0,0,0).

Used for scatterer (electron, nucleus) density generation.

CrystMatrix_REAL ObjCryst::ScatteringPowerAtom::GetResonantScattFactImag	(	const ScatteringData &	data,

	)		const

virtual

Get the imaginary part of the resonant scattering factor.

Returns: a matrix where each row corresponds to each wavelength (currently only monochromatic experiments are made so there is only one row), and each column corresponds to each reflection only if the scattering term is anisotropic, which is not the case so far...

Parameters

data	the ScatteringData object, giving access to all the reflections, and a list of wavelengths.
spgSymPosIndex	if the ScatteringPower is anisotropic, then the different symmetrics will not have the same scattering power for all reflections. This parameter is the index of the symmetric position in the Spacegroup. If spgSymPosIndex=-1, the isotropic values are returned.

Warning: There is no anisotropic code yet, so spgSymPosIndex is simply ignored so far , but the design of this function is general for any anisotropic scattering.
