_atom_type_scat.dispersion
Name:_atom_type_scat.dispersion
Definition:
The anomalous dispersion scattering factor in its complex form
for this atom type and radiation by _diffrn_radiation_wavelength.value.
Type: Complex
Units: none
Evaluation method:
With s as atom_type_scat
d = Complex( s.dispersion_real, s.dispersion_imag )
if(_reflns.apply_dispersion_to_Fcalc == 'no') d = 0.
_atom_type_scat.dispersion = d
Category:
