_atom_type_scat.dispersion_imag
Name:_atom_type_scat.dispersion_imag
Aliases:
_atom_type_scat_dispersion_imag
_atom_type.scat_dispersion_imag
Definition:
The imaginary component of the anomalous-dispersion scattering factor
for this atom type and the radiation specified by
_diffrn_radiation_wavelength.value.
Type: Real
Units: none
Evaluation method:
With q as atom_type_scat
If ( _diffrn_radiation.type[0:2] == 'Cu' ) a = q.dispersion_imag_Cu
If ( _diffrn_radiation.type[0:2] == 'Mo' ) a = q.dispersion_imag_Mo
_atom_type_scat.dispersion_imag = a
Category:
atom_type_scat
