Differential incoherent scattering cross sections of 661.6 keV gamma rays

Abstract

Differential incoherent scattering cross sections of 661.6 keV gamma rays in the elements Mg, Ca, Cu, Sn and Pb and in the compounds MgO, CaO, NaCl, MgF2, NiO, KCl, NaNO3, MgCl2, CuCl, CaCO3, KNO3, NaBr, KBr, CaCl2, SrF2, ZrO2, Li2SO4H2O, Zr(NO3)45H2O, KI, V2O5, MgSO36H2O, MgSO47H2O, CoSO36H2O, SrCl26H2O, BaCl22H2O and Pb(HCO2)2 at 4 and 6 degrees have been measured with a shadow-cone geometry set-up. Using these cross sections and the mixture rule, the cross sections of the gaseous elements N, O, F, and Cl, the liquid element Br and the solid elements Li, C, Na, Mg, S, K, Ca, V, Co, Ni, Cu, Sr, Zr, I, Ba and Pb are derived. These derived cross sections are compared with the theoretically calculated cross sections and are found to be in good agreement.
