https://doi.org/10.1007/978-3-7091-3686-7This chapter deals with the specific and well defined task: determining structure factor amplitudes from measurements of Bragg reflections on single crystals using X-ray or neutron radiation. It may however be worthwhile first to discuss in more general terms the optimal conditions for measuring any piece of information.

Influence of Trauma and Disease,For an unpolarised neutron beam the diffracted intensities are proportional to the sum of the squares of the structure factors . where F. denotes the nuclear structure factor and . the component of the magnetic structure factor in the plane perpendicular to the scattering vector ..

An Electrostatic Description of Chemical BindingThe reasons for our interest in charge-density maps are probably extremely varied. But surely one important reason is the hope of learning something about chemical binding. For this purpose it is useful to think of the chemical bond in electrostatic terms.
