[PDF][PDF] On Compton scattering as a source of background in coherent diffraction imaging experiments
O Bikondoa, D Carbone - Journal of Synchrotron Radiation, 2021 - journals.iucr.org
Compton scattering is generally neglected in diffraction experiments because the incoherent
radiation it generates does not give rise to interference effects and therefore is negligible at …
