WebCOMPTON SCATTERING OF X-RAYS FROM NONSPHERICAL CHARGE DISTRIBUTIONS Full Record Related Research Abstract The Waller-Hartree theory for the incoherent Compton scattering of x rays is extended to include the effects, of the inherent nonsphericity of atomic charge distributions. WebThe intensity at low q ($0.01 Å À1) varied as a quadratic function of P H and indicated a minimum value at P H = 30%, which can be explained by the scattering contrast between SP and SBR. The scattering intensity at high q ($0.3 Å À1 ) decreased with increasing P H , which is attributed to the incoherent scattering from hydrogen. cisco security acquisitions
