Abstract
Coherent scattering cross sections for the elements Pr, Sm, Gd, Dy, Ho, Er Pt, Au and Ph have been measured at the excitation energy 16.58 keV. The measured cross sections are compared with the normalised integrated scattering cross section values calculated using relativistic, non-relativistic and relativistic modified form factors. Atomic form factors are extracted from the measured cross sections at q = 0.9457 h Angstrom(-1). The results were compared with the different formalisms of form factor theory and their validity at a = 0.9457 h Angstrom(-1) is thoroughly discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
