A study of molecular correlations observed in the small-angle photon scattering distributions of 60 keV photons interacting with low-atomic-number media

Abstract A variant of the multisection filter and annular target geometry, with a designed angular acceptance of ±0.5°, has been utilised in measuring accurate. O(5%), absolute total differential scattering cross sections of 60 keV photons for H 2 O, methyl methacrylate (C 5 H 8 O 2 ) n and nylon-6 (C 12 H 22 O 3 N 2 ) n in the angular scattering range of 2°–10°. The effects of molecular correlations manifest, to varying degree, in strong forward peaking of the scattered photon distribution. Comparison is made with available experiment and theory.
