Incoherent scattering of 59.54keV γ-rays at small momentum transfers

Whole atom differential incoherent scattering cross sections for 59.54 keV null γ -rays were measured for a number of elements in the region 29⩽ Z⩽ 82 at scattering angles 90, 60, 45 and 30° employing a reflection geometry set up and a graded shielding arrangement. A 6 cm 3 null HPGe detector was used to detect the scattered null γ -rays. All the 49 cross sections reported in this paper constitute the first experimental measurement and serve to...
